WEBVTT 00:00:00.000 --> 00:00:03.399 Welcome to today's Deep Dive. We are really glad 00:00:03.399 --> 00:00:04.820 you're joining us for this one. Yeah, this is 00:00:04.820 --> 00:00:06.500 going to be a fun one. Have you ever stopped 00:00:06.500 --> 00:00:09.039 to think about how much weight a single word 00:00:09.039 --> 00:00:12.419 can carry? And I don't mean some complex, multi 00:00:12.419 --> 00:00:15.880 -syllabic piece of academic jargon. Just one 00:00:15.880 --> 00:00:21.000 short, incredibly common, everyday combination 00:00:21.000 --> 00:00:23.179 of letters. Right. The kind of word you don't 00:00:23.179 --> 00:00:26.320 even think about using. Exactly. Today, we're 00:00:26.320 --> 00:00:29.120 looking at a specific five -letter word. that 00:00:29.120 --> 00:00:31.879 you definitely know you use it. And if we're 00:00:31.879 --> 00:00:33.479 being completely honest with ourselves, you probably 00:00:33.479 --> 00:00:35.520 cringe just a little bit when you hear it. That 00:00:35.520 --> 00:00:38.219 word is roach. It really is a word that instantly 00:00:38.219 --> 00:00:40.979 provokes this visceral reaction. I mean, when 00:00:40.979 --> 00:00:42.899 you hear it, your mind immediately goes to a 00:00:42.899 --> 00:00:45.820 very specific scurrying place. Usually somewhere 00:00:45.820 --> 00:00:47.259 near the refrigerator or two in the morning. 00:00:47.359 --> 00:00:50.259 Yeah. Exactly. But the reality of this word, 00:00:50.320 --> 00:00:52.820 the actual linguistic footprint it leaves behind, 00:00:53.020 --> 00:00:55.219 is so much broader. And frankly, it's so much 00:00:55.219 --> 00:00:57.640 stranger than that initial instinct. And that 00:00:57.640 --> 00:01:00.259 brings us to the entire mission of our deep dive 00:01:00.259 --> 00:01:03.079 today. We are looking at the Wikipedia disambiguation 00:01:03.079 --> 00:01:06.000 page for the word roach. Which is quite the document. 00:01:06.140 --> 00:01:08.560 It really is. Now, if you aren't super familiar 00:01:08.560 --> 00:01:11.200 with the mechanics of Wikipedia, a disambiguation 00:01:11.200 --> 00:01:13.920 page is basically the Internet's way of playing 00:01:13.920 --> 00:01:16.620 traffic cop. It's a directory that routes you 00:01:16.620 --> 00:01:19.060 to all the different articles that happen to 00:01:19.060 --> 00:01:21.620 share the exact same title. You type in a word 00:01:21.620 --> 00:01:24.019 and the site basically says, hold on, which one 00:01:24.019 --> 00:01:26.480 did you mean? Right. And the disambiguation page 00:01:26.480 --> 00:01:29.760 for Roach is this absolute sprawling map of human 00:01:29.760 --> 00:01:32.980 experience. We're going to unpack how this single 00:01:32.980 --> 00:01:35.700 word stretches across the animal kingdom, forgotten 00:01:35.700 --> 00:01:39.099 geography, pop culture, niche technical fields, 00:01:39.299 --> 00:01:42.060 and even international law. Okay. Let's unpack 00:01:42.060 --> 00:01:45.640 this. You know, disambiguation pages are in a 00:01:45.640 --> 00:01:48.480 lot of ways these accidental monuments to human 00:01:48.480 --> 00:01:50.900 language. They aren't written as cohesive narratives 00:01:50.900 --> 00:01:53.560 at all. They're literally just lists. Exactly. 00:01:53.819 --> 00:01:56.659 Lists designed for navigation. But when you look 00:01:56.659 --> 00:01:58.840 at them closely, they show how a single string 00:01:58.840 --> 00:02:01.420 of letters, purely by coincidence or maybe historical 00:02:01.420 --> 00:02:04.200 drift, can mean wildly different things depending 00:02:04.200 --> 00:02:05.879 on where you are standing and what you happen 00:02:05.879 --> 00:02:07.700 to do for a living. It's like an archaeological 00:02:07.700 --> 00:02:10.909 dig. It is. They act like an archaeological dig 00:02:10.909 --> 00:02:14.009 of human priorities. It reminds us that language 00:02:14.009 --> 00:02:17.669 is incredibly messy, highly adaptable, and constantly 00:02:17.669 --> 00:02:20.310 being recycled. Well, let's start that dig in 00:02:20.310 --> 00:02:22.530 the natural world. Yeah. Because we have to acknowledge 00:02:22.530 --> 00:02:24.650 the insect in the room right off the bat. Yeah, 00:02:24.689 --> 00:02:26.789 we can't ignore it. When I say the word roach, 00:02:26.810 --> 00:02:28.969 the very first thing you picture is a cockroach. 00:02:29.509 --> 00:02:31.490 According to our source material that represents 00:02:31.490 --> 00:02:34.110 various insect species in the scientific order 00:02:34.670 --> 00:02:37.729 The ultimate survivors. The household pest we 00:02:37.729 --> 00:02:40.689 all know and generally despise. But our source 00:02:40.689 --> 00:02:43.449 also reveals that the natural world has an entirely 00:02:43.449 --> 00:02:46.210 different, vastly more diverse definition for 00:02:46.210 --> 00:02:49.030 this word. Right. If you step away from the kitchen 00:02:49.030 --> 00:02:52.430 floor and look toward the aquatic world, roach 00:02:52.430 --> 00:02:54.930 takes on a completely different biological identity. 00:02:55.289 --> 00:02:57.689 It's a fish. It is a fish. More specifically, 00:02:57.889 --> 00:03:01.060 the common roach. Known scientifically as Rudalis 00:03:01.060 --> 00:03:03.840 rudalis. It's a fish that lives in fresh and 00:03:03.840 --> 00:03:06.180 brackish water, and it belongs to the family 00:03:06.180 --> 00:03:08.419 Cyprinidae. I have to pause you there for a second. 00:03:08.479 --> 00:03:10.560 Just for those of us who aren't marine biologists, 00:03:10.819 --> 00:03:14.000 what exactly do we mean by brackish water? Oh, 00:03:14.020 --> 00:03:16.699 fair question. Brackish water is essentially 00:03:16.699 --> 00:03:19.479 the middle ground between freshwater and saltwater. 00:03:19.639 --> 00:03:21.969 Like where a river meets the sea. Exactly. You 00:03:21.969 --> 00:03:24.729 usually find it in estuaries. So this fish is 00:03:24.729 --> 00:03:26.889 incredibly adaptable. It can handle that mixed 00:03:26.889 --> 00:03:29.150 salinity environment without a problem. Okay. 00:03:29.189 --> 00:03:31.669 So we have the common roach. Swim around these 00:03:31.669 --> 00:03:34.310 estuaries. Is that it? Is it just one isolated 00:03:34.310 --> 00:03:37.189 species of fish that happens to share a name 00:03:37.189 --> 00:03:40.250 with a bug? Not even close. This is a massive 00:03:40.250 --> 00:03:42.789 global category. There's a whole genus of fishes 00:03:42.789 --> 00:03:45.310 literally called rutilis, which are just known 00:03:45.310 --> 00:03:48.289 collectively as roaches. Wow. But the source 00:03:48.289 --> 00:03:51.169 shows us it doesn't even stop with that one genus. 00:03:51.169 --> 00:03:53.870 The term roach is applied to members of several 00:03:53.870 --> 00:03:57.110 other leucicid genera all across the globe. Okay, 00:03:57.150 --> 00:04:00.530 another quick definition check. Leucicid. That 00:04:00.530 --> 00:04:03.310 sounds like a medication or something. It really 00:04:03.310 --> 00:04:04.909 does sound like something you'd get a prescription 00:04:04.909 --> 00:04:07.889 for. But in biology, the leucisches are a specific 00:04:07.889 --> 00:04:10.949 family of freshwater fish. They are very closely 00:04:10.949 --> 00:04:14.379 related to true minnows. Okay, got it. And within 00:04:14.379 --> 00:04:16.699 this broad family, the label roach gets applied 00:04:16.699 --> 00:04:19.899 everywhere. You have the genus Leukos, which 00:04:19.899 --> 00:04:21.839 is found in southern Europe. You have the genus 00:04:21.839 --> 00:04:24.519 Sarmerudelus, also swimming around in the streams 00:04:24.519 --> 00:04:26.100 of southern Europe. And it jumps continents, 00:04:26.319 --> 00:04:28.680 right? It does. Jumping across the Atlantic Ocean, 00:04:28.819 --> 00:04:31.000 you have the genus Hesperoleukos, which is found 00:04:31.000 --> 00:04:34.160 all the way over in western North America. The 00:04:34.160 --> 00:04:37.259 source material also points us to... Related 00:04:37.259 --> 00:04:40.100 small fish that fall under this umbrella, like 00:04:40.100 --> 00:04:43.259 the dace and the shiner. It is such a stark contrast. 00:04:43.519 --> 00:04:46.740 On land, the word makes people shudder. It represents 00:04:46.740 --> 00:04:49.199 something we actively pay exterminators to keep 00:04:49.199 --> 00:04:51.759 out of our homes. The ultimate unwanted guest. 00:04:52.120 --> 00:04:55.279 Right. But down in the water. The word represents 00:04:55.279 --> 00:04:58.100 this sprawling, diverse group of aquatic species 00:04:58.100 --> 00:05:00.639 spanning from the streams of Europe to the waters 00:05:00.639 --> 00:05:02.620 of North America. It's just a completely standard, 00:05:02.800 --> 00:05:05.300 neutral classification. Yeah, a totally different 00:05:05.300 --> 00:05:07.680 vibe. It really makes you consider how the exact 00:05:07.680 --> 00:05:10.980 same phonetic sound, that hard R and that harsh 00:05:10.980 --> 00:05:14.220 tri at the end, can describe completely unrelated 00:05:14.220 --> 00:05:16.759 branches of the animal kingdom. You have the 00:05:16.759 --> 00:05:19.040 Bladidea on one side and the Sopranidae on the 00:05:19.040 --> 00:05:21.139 other. Completely different worlds, exact same 00:05:21.139 --> 00:05:24.089 word. It highlights the entirely arbitrary. nature 00:05:24.089 --> 00:05:27.990 of common names in biology how so well a scientific 00:05:27.990 --> 00:05:31.029 latin name is precise right it tells you exactly 00:05:31.029 --> 00:05:33.230 where a creature fits in the evolutionary tree 00:05:33.230 --> 00:05:36.089 but a common name like roach is just a label 00:05:36.589 --> 00:05:38.670 It gets stuck to whatever local creature somewhat 00:05:38.670 --> 00:05:42.110 fits the bill. Or it simply inherits the title 00:05:42.110 --> 00:05:44.129 through generations of fishermen pointing at 00:05:44.129 --> 00:05:46.529 the water. Just a localized shorthand. Exactly. 00:05:46.569 --> 00:05:48.870 A localized shorthand that eventually just gets 00:05:48.870 --> 00:05:51.430 codified into the dictionary. Speaking of localized 00:05:51.430 --> 00:05:54.149 shorthand, let's move from biology into geography. 00:05:54.670 --> 00:05:56.990 Because this word is physically stamped across 00:05:56.990 --> 00:05:59.019 the map. I'm going to take you on a bit of a 00:05:59.019 --> 00:06:01.620 geographical tour right now because people actually 00:06:01.620 --> 00:06:04.639 live or in some cases used to live in places 00:06:04.639 --> 00:06:06.660 called Roche. This is where it gets kind of surreal. 00:06:06.899 --> 00:06:09.660 It really does. Let's look at the United States. 00:06:10.120 --> 00:06:12.680 We have Roche, Missouri, which is an unincorporated 00:06:12.680 --> 00:06:14.560 community. We also have Roche, West Virginia, 00:06:14.759 --> 00:06:17.399 another unincorporated community. And then there's 00:06:17.399 --> 00:06:20.360 Roche, Nevada, which our source lists explicitly 00:06:20.360 --> 00:06:22.980 as a ghost town. I think we need to linger on 00:06:22.980 --> 00:06:24.959 Roach, Nevada for a moment. Just think about 00:06:24.959 --> 00:06:28.379 the evocative nature of that. A ghost town named 00:06:28.379 --> 00:06:31.019 Roach. It really paints a picture. It carries 00:06:31.019 --> 00:06:34.420 this almost cinematic, desolate sense of abandonment. 00:06:34.560 --> 00:06:36.819 You can almost picture the tumbleweeds blowing 00:06:36.819 --> 00:06:39.920 through empty dirt streets, the rusted out saloon 00:06:39.920 --> 00:06:42.519 doors banging in the wind. But it makes you wonder, 00:06:42.660 --> 00:06:47.060 who founded a town and decided, yes, Roach. That 00:06:47.060 --> 00:06:49.120 is the name that will draw on the settlers and 00:06:49.120 --> 00:06:52.060 build our thriving metropolis. It's a fascinating 00:06:52.060 --> 00:06:54.459 question. Often these places were named after 00:06:54.459 --> 00:06:57.660 a single person, a founder, a postmaster, or 00:06:57.660 --> 00:07:00.220 a railroad foreman whose last name just happened 00:07:00.220 --> 00:07:02.100 to be Roach. So they weren't naming it after 00:07:02.100 --> 00:07:04.439 the bug. Right. They were naming it after a guy 00:07:04.439 --> 00:07:07.139 named Frank or something. But once the town dries 00:07:07.139 --> 00:07:09.420 up and the people leave, the context entirely 00:07:09.420 --> 00:07:12.939 evaporates. All that remains is this slightly 00:07:12.939 --> 00:07:16.319 melancholic, unglamorous word attached to a ruin 00:07:16.319 --> 00:07:19.459 in the desert. It feels incredibly fitting for 00:07:19.459 --> 00:07:21.759 a place that time and industry have completely 00:07:21.759 --> 00:07:24.079 left behind. But the name doesn't just stick 00:07:24.079 --> 00:07:27.300 to the dry, dusty land. It actually follows the 00:07:27.300 --> 00:07:29.600 water, too, which makes perfect sense given our 00:07:29.600 --> 00:07:32.029 earlier conversation about the fish. Yep. Back 00:07:32.029 --> 00:07:34.430 to the water. The source traces the name across 00:07:34.430 --> 00:07:37.930 multiple flowing waterways. In Maine, located 00:07:37.930 --> 00:07:40.110 in Piscataquist County, you'll find the Roach 00:07:40.110 --> 00:07:43.009 River. Down in Virginia, there is another Roach 00:07:43.009 --> 00:07:45.449 River, which serves as a tributary of the North 00:07:45.449 --> 00:07:47.529 Fork -Rivanna River. And it crosses the ocean 00:07:47.529 --> 00:07:50.350 again. It does. Over in Essex, England, you have 00:07:50.350 --> 00:07:52.649 the River Roach. So what does this all mean? 00:07:52.829 --> 00:07:55.069 It illustrates how names settle into the landscape. 00:07:56.009 --> 00:07:58.110 Geography acts as a living record of linguistic 00:07:58.110 --> 00:08:01.319 choices. Sometimes names stick around for centuries, 00:08:01.560 --> 00:08:03.899 flowing continuously like the River Roach in 00:08:03.899 --> 00:08:06.399 Essex. Sometimes they fade away into nothing 00:08:06.399 --> 00:08:08.819 but foundations and memories like the ghost town 00:08:08.819 --> 00:08:12.339 in Nevada. And sometimes human history just decides 00:08:12.339 --> 00:08:14.920 to write over them entirely. Exactly. We actually 00:08:14.920 --> 00:08:16.680 have a great example of that from the source 00:08:16.680 --> 00:08:19.399 material. We do. Up in Saskatchewan, Canada, 00:08:19.660 --> 00:08:22.459 Roach was actually the former name of a place 00:08:22.459 --> 00:08:24.899 now known as the rural municipality of Leroy 00:08:24.899 --> 00:08:28.300 No. 339. They completely swapped it out. They 00:08:28.300 --> 00:08:30.810 did. It's funny to think about what must have 00:08:30.810 --> 00:08:32.850 happened there. Did the local residents eventually 00:08:32.850 --> 00:08:35.490 feel so burdened by the name that a place like 00:08:35.490 --> 00:08:38.429 a Canadian municipality felt forced to rebrand? 00:08:38.919 --> 00:08:40.980 It makes you wonder. You can almost imagine the 00:08:40.980 --> 00:08:43.240 town hall meeting where they decided that Leroy 00:08:43.240 --> 00:08:46.700 number 339 was somehow a much better PR move 00:08:46.700 --> 00:08:49.399 for a rural municipality than Roach. It shows 00:08:49.399 --> 00:08:51.860 that place names aren't permanent. They are subject 00:08:51.860 --> 00:08:54.139 to the whims of the people who live there. If 00:08:54.139 --> 00:08:57.139 a name hurts tourism or just gets tired, a community 00:08:57.139 --> 00:08:59.539 will simply erase it from the map and start over. 00:08:59.720 --> 00:09:01.799 And it isn't just places that carry this name. 00:09:02.080 --> 00:09:05.309 It's people, too. Let's look at the real living 00:09:05.309 --> 00:09:08.289 individuals who carry this moniker. Our source 00:09:08.289 --> 00:09:10.710 notes there is an entire directory, a whole list 00:09:10.710 --> 00:09:13.370 of people who bear the surname Roach. There are 00:09:13.370 --> 00:09:15.610 some really notable ones on that list. There 00:09:15.610 --> 00:09:18.289 are. A few specific individuals are highlighted. 00:09:18.629 --> 00:09:21.190 There's the famous celebrity stylist Law Roach. 00:09:21.370 --> 00:09:23.769 We have an American rapper and hip -hop artist 00:09:23.769 --> 00:09:27.029 born in 1988 who goes simply by the stage name 00:09:27.029 --> 00:09:30.879 Roach. Just Roach. Just Roach. The source also 00:09:30.879 --> 00:09:33.179 points out the surname Roach, spelled with an 00:09:33.179 --> 00:09:35.519 E on the end, which is shared by several notable 00:09:35.519 --> 00:09:38.059 actors. And then there was a truly fascinating 00:09:38.059 --> 00:09:40.940 historical entry. A man named Roach Stewart, 00:09:41.100 --> 00:09:45.179 who lived from 1881 to 1948. And get this, he 00:09:45.179 --> 00:09:47.460 was both a college football player and an attorney. 00:09:47.879 --> 00:09:50.120 The variety of lives lived under this one name 00:09:50.120 --> 00:09:52.779 is just remarkable. You have an early 20th century 00:09:52.779 --> 00:09:55.500 college football player arguing cases in a courtroom 00:09:55.500 --> 00:09:57.960 right alongside a modern hip hop artist and a 00:09:57.960 --> 00:10:00.639 high fashion stylist. It proves that a name doesn't 00:10:00.639 --> 00:10:03.480 dictate your destiny. Exactly. But when we shift 00:10:03.480 --> 00:10:05.879 our focus to how the name is utilized in fiction 00:10:05.879 --> 00:10:08.340 and pop culture, a very different pattern emerges. 00:10:08.440 --> 00:10:10.179 Yes, absolutely. The fictional applications are 00:10:10.179 --> 00:10:12.419 incredibly specific. They lean into a very particular 00:10:12.419 --> 00:10:14.960 vibe. Listen to this lineup from the disambiguation 00:10:14.960 --> 00:10:17.179 page. You have a fictional character named... 00:10:17.200 --> 00:10:20.399 Roach from the classic 1991 crime action film 00:10:20.399 --> 00:10:22.620 Point Break. A great movie. On a lighter note, 00:10:22.700 --> 00:10:25.179 there's a character in the animated series Super 00:10:25.179 --> 00:10:28.399 Noobs, simply named Roach. And then we dive deep 00:10:28.399 --> 00:10:31.059 into the gaming world. In the sci -fi strategy 00:10:31.059 --> 00:10:34.940 game StarCraft II, a Roach is a specific, heavily 00:10:34.940 --> 00:10:38.240 armored alien unit for the Zerg faction. And 00:10:38.240 --> 00:10:40.259 it's not just 90s action movies and sci -fi. 00:10:40.279 --> 00:10:42.820 It crossed over into massive military gaming 00:10:42.820 --> 00:10:46.149 franchises as well. In Call of Duty, Modern Warfare 00:10:46.149 --> 00:10:48.669 2, there's a playable special operations character 00:10:48.669 --> 00:10:52.029 named Gary Roach Sanderson. We also see a significant 00:10:52.029 --> 00:10:54.769 footprint in the music world. There's the American 00:10:54.769 --> 00:10:57.549 rock band Papa Roach, who've been a staple of 00:10:57.549 --> 00:11:00.230 their genre for decades. A massive band. And 00:11:00.230 --> 00:11:02.370 in the realm of classic hip -hop, the source 00:11:02.370 --> 00:11:06.110 highlights Dr. Dre's iconic 1992 album, The Chronic. 00:11:06.490 --> 00:11:08.889 The final track on that album is actually titled 00:11:08.889 --> 00:11:11.289 The Roach, the chronic outro. It's worth asking 00:11:11.289 --> 00:11:13.610 yourself why creators choose this specific name 00:11:13.610 --> 00:11:15.529 for their characters, their bands, or their songs. 00:11:15.750 --> 00:11:17.769 Because it's not an accident. It's definitely 00:11:17.769 --> 00:11:19.929 not an accident. Whether it's a bank robber in 00:11:19.929 --> 00:11:22.110 Point Break, Gary Sanderson in Call of Duty, 00:11:22.289 --> 00:11:25.110 or an alien unit in Starcraft, the word roach 00:11:25.110 --> 00:11:27.870 carries an inherent toughness. It implies survival. 00:11:28.029 --> 00:11:31.289 Exactly. It implies grit. Being hard to kill, 00:11:31.429 --> 00:11:34.730 operating in the shadows, it's incredibly memorable 00:11:34.730 --> 00:11:37.970 precisely because it's a bit abrasive. It makes 00:11:37.970 --> 00:11:40.110 you wonder, though, do the creators of StarCraft 00:11:40.110 --> 00:11:42.490 know they are tapping into the exact same cultural 00:11:42.490 --> 00:11:46.049 nerve as a 90s hip -hop album? Or is it just 00:11:46.049 --> 00:11:48.429 a subconscious linguistic shortcut? That's the 00:11:48.429 --> 00:11:51.370 question. You hear the name, and you instantly 00:11:51.370 --> 00:11:53.610 know you aren't dealing with someone soft or 00:11:53.610 --> 00:11:56.200 polished. It sounds like what it is. It's almost 00:11:56.200 --> 00:11:59.080 certainly a subconscious shortcut. Creators leverage 00:11:59.080 --> 00:12:01.320 the cultural baggage of that word to immediately 00:12:01.320 --> 00:12:03.539 tell you something about the character or the 00:12:03.539 --> 00:12:07.100 music before you even experience it. If a soldier 00:12:07.100 --> 00:12:09.759 is nicknamed Roach, you instantly understand 00:12:09.759 --> 00:12:12.080 that his defining characteristic is that he survives 00:12:12.080 --> 00:12:14.360 things that should kill him. Here's where it 00:12:14.360 --> 00:12:16.500 gets really interesting, though. The word doesn't 00:12:16.500 --> 00:12:19.509 just stop at gritty pop culture. It finds its 00:12:19.509 --> 00:12:22.210 way into the most unexpected, highly specialized 00:12:22.210 --> 00:12:25.009 corners of human activity. The miscellany. The 00:12:25.009 --> 00:12:27.409 miscellany section of this disambiguation page 00:12:27.409 --> 00:12:30.870 is truly a study in wild contrasts. I want to 00:12:30.870 --> 00:12:32.809 put two things side by side that our source material 00:12:32.809 --> 00:12:34.809 lists right next to each other because it broke 00:12:34.809 --> 00:12:36.570 my brain a little bit. Let's hear it. On one 00:12:36.570 --> 00:12:39.450 hand, you have a landmark 2007 High Court of 00:12:39.450 --> 00:12:42.710 Australia case. Its title, Roach v. Electoral 00:12:42.710 --> 00:12:45.559 Commissioner. Okay. Very serious. Extremely serious. 00:12:45.720 --> 00:12:48.399 And on the other hand, just to scroll away, you 00:12:48.399 --> 00:12:50.620 have a piece of Russian children's literature 00:12:50.620 --> 00:12:53.679 from 1923 written by a poet named Kornichakovsky 00:12:53.679 --> 00:12:56.879 titled The Roach. which is sometimes translated 00:12:56.879 --> 00:13:00.539 as the giant cockroach. That juxtaposition perfectly 00:13:00.539 --> 00:13:02.279 encapsulates what we were talking about earlier 00:13:02.279 --> 00:13:04.940 with Wikipedia acting as an archaeological dig. 00:13:05.200 --> 00:13:07.399 Think about the gravity of the High Court of 00:13:07.399 --> 00:13:10.100 Australia. The absolute pinnacle of a nation's 00:13:10.100 --> 00:13:12.580 judicial system. Right. Dealing with a landmark 00:13:12.580 --> 00:13:15.259 constitutional case titled Roach v. Electoral 00:13:15.259 --> 00:13:17.720 Commissioner. You picture the halls of justice 00:13:17.720 --> 00:13:21.220 sweeping legal precedents, wigs, robes and mahogany. 00:13:21.679 --> 00:13:24.100 And sharing the exact same digital anchor is 00:13:24.100 --> 00:13:26.299 a whimsical, rhyming Russian children's poem 00:13:26.299 --> 00:13:29.700 from the 1920s about a giant insect. It really 00:13:29.700 --> 00:13:31.700 highlights how a database flattens hierarchy. 00:13:32.379 --> 00:13:35.120 International constitutional law and a child's 00:13:35.120 --> 00:13:37.620 bedtime story weigh exactly the same in the eyes 00:13:37.620 --> 00:13:39.940 of a search engine. They are just data points 00:13:39.940 --> 00:13:42.519 sharing a five letter string. And the wildly 00:13:42.519 --> 00:13:45.120 specific terminology just keeps going. Let's 00:13:45.120 --> 00:13:46.879 slow down and look at some of these incredibly 00:13:46.879 --> 00:13:49.399 niche uses of the word because they are fascinating. 00:13:49.840 --> 00:13:53.039 Let's look at the equestrian world. Horses. Horses. 00:13:53.480 --> 00:13:56.820 If you're grooming horses, roaching is a very 00:13:56.820 --> 00:13:59.840 specific way of styling the mane of a horse where 00:13:59.840 --> 00:14:02.960 it is shaved completely off. Furthermore, a roachback 00:14:02.960 --> 00:14:05.850 refers to a specific type of conformation. or 00:14:05.850 --> 00:14:08.389 physical structure, of a horse's back, where 00:14:08.389 --> 00:14:10.610 it has a convex curvature. And if you leave the 00:14:10.610 --> 00:14:12.610 stables and head out to sea, the terminology 00:14:12.610 --> 00:14:14.970 comes with you, but it changes its meaning entirely. 00:14:15.669 --> 00:14:18.549 In sailing, a roach refers to an arc of extra 00:14:18.549 --> 00:14:21.370 material on the leech of a sail. Wait, for those 00:14:21.370 --> 00:14:23.470 of us whose nautical experience is limited to 00:14:23.470 --> 00:14:25.830 watching pirate movies, what part of the sail 00:14:25.830 --> 00:14:28.090 is the leech? Ah, right. The leech is simply 00:14:28.090 --> 00:14:30.389 the back edge of a sail. The back edge. Right. 00:14:30.470 --> 00:14:32.529 It's the trailing edge that catches the wind 00:14:32.529 --> 00:14:35.879 last. So a roach in sailing is an extra curve 00:14:35.879 --> 00:14:38.559 of fabric added to that back edge to catch a 00:14:38.559 --> 00:14:41.360 bit more wind and provide extra power. It has 00:14:41.360 --> 00:14:44.139 absolutely nothing to do with bugs or fish. Amazing. 00:14:44.480 --> 00:14:47.539 Okay, let's dig into the earth. In geology, there 00:14:47.539 --> 00:14:50.500 is something called roach stone. It's a specific 00:14:50.500 --> 00:14:52.539 type of Portland limestone that is characterized 00:14:52.539 --> 00:14:55.820 by having many fossilized shell fragments embedded 00:14:55.820 --> 00:14:58.350 right within it. It's used in architecture. From 00:14:58.350 --> 00:15:01.250 sails to stone. From sails to stone. And looking 00:15:01.250 --> 00:15:03.289 at traditional culture, our source notes that 00:15:03.289 --> 00:15:05.409 a roach is the name for a traditional Native 00:15:05.409 --> 00:15:07.889 American headdress. It was usually made out of 00:15:07.889 --> 00:15:10.289 porcupine hair. And finally, returning to the 00:15:10.289 --> 00:15:12.289 realm of recreation and the counterculture we 00:15:12.289 --> 00:15:15.070 touched on with Dr. Dre's album, a roach is widely 00:15:15.070 --> 00:15:17.230 known as the term for the butt of a marijuana 00:15:17.230 --> 00:15:19.830 cigarette. So we have shaved horse manes, the 00:15:19.830 --> 00:15:22.669 back edge of a sail, fossilized shells and architectural 00:15:22.669 --> 00:15:25.970 stone, porcupine hair, headdresses, and the end 00:15:25.970 --> 00:15:28.470 of a joint. It is dizzying how many different 00:15:28.470 --> 00:15:30.629 things this word means depending on who is saying 00:15:30.629 --> 00:15:32.809 it. If we connect this to the bigger picture, 00:15:33.029 --> 00:15:35.490 it reveals exactly how specialized communities 00:15:35.490 --> 00:15:39.009 operate. Sailors, geologists, horse groomers, 00:15:39.210 --> 00:15:41.610 Native American artisans, canvas enthusiasts. 00:15:41.970 --> 00:15:45.210 These groups all develop their own internal languages. 00:15:45.549 --> 00:15:48.169 They need specific words for specific things. 00:15:48.370 --> 00:15:51.649 Exactly. And what they often do is hijack an 00:15:51.649 --> 00:15:54.190 everyday word and assign it a highly technical, 00:15:54.409 --> 00:15:57.830 rigidly defined meaning. That meaning makes perfect 00:15:57.830 --> 00:16:00.809 sense inside their specific community, but it 00:16:00.809 --> 00:16:03.549 is completely opaque to anyone outside of it. 00:16:03.629 --> 00:16:05.809 It acts as a tribal marker. A tribal marker, 00:16:05.950 --> 00:16:08.850 yes. If a geologist talks to a sailor about a 00:16:08.850 --> 00:16:11.070 roach, they are having two entirely different 00:16:11.070 --> 00:16:13.309 conversations, and neither of them is talking 00:16:13.309 --> 00:16:15.429 about the insect on the kitchen floor. It's a 00:16:15.429 --> 00:16:17.409 perfect example of how language fragments and 00:16:17.409 --> 00:16:20.029 specializes. The word roach is like a skeleton 00:16:20.029 --> 00:16:22.470 key that opens a dozen different locks, but you 00:16:22.470 --> 00:16:24.250 have to know exactly which door you're standing 00:16:24.250 --> 00:16:26.620 in front of. This raises an important question 00:16:26.620 --> 00:16:29.480 about how we consume information today. We often 00:16:29.480 --> 00:16:31.860 talk about information overload as this modern 00:16:31.860 --> 00:16:34.220 horizontal phenomenon. Like we're drowning in 00:16:34.220 --> 00:16:36.679 too many articles or too many news feeds. Right, 00:16:36.820 --> 00:16:38.940 too many distinct data points scrolling past 00:16:38.940 --> 00:16:42.100 our eyes. But this disambiguation page shows 00:16:42.100 --> 00:16:44.379 us that information overload isn't just horizontal, 00:16:44.720 --> 00:16:47.919 it's vertical. It's hidden right there inside 00:16:47.919 --> 00:16:51.000 a single everyday word. You don't even need to 00:16:51.000 --> 00:16:53.659 read... a hundred different articles to be overwhelmed 00:16:53.659 --> 00:16:55.659 by information. You just have to look at all 00:16:55.659 --> 00:16:58.100 the secret parallel definitions packed into five 00:16:58.100 --> 00:17:00.320 letters. Let's take a moment to look back at 00:17:00.320 --> 00:17:02.639 the sheer scale of the domains of human experience 00:17:02.639 --> 00:17:06.359 we just crossed using only one word. We started 00:17:06.359 --> 00:17:09.359 with the revulsion of biology, the Bladderdea 00:17:09.359 --> 00:17:11.980 insect, the household cockroach. The bug we all 00:17:11.980 --> 00:17:14.430 know. The bug we all know. Then we immediately 00:17:14.430 --> 00:17:16.930 washed that away with the Sopranidae fish, the 00:17:16.930 --> 00:17:18.990 common roach, swimming through the brackish waters 00:17:18.990 --> 00:17:22.789 of Europe alongside its lucid relatives. We traveled 00:17:22.789 --> 00:17:24.990 across a map of forgotten ghost towns in the 00:17:24.990 --> 00:17:28.250 Nevada desert, flowing rivers in Maine, and remembered 00:17:28.250 --> 00:17:31.190 the town hall meetings of a renamed rural municipality 00:17:31.190 --> 00:17:34.319 in Canada. We charted the human element from 00:17:34.319 --> 00:17:37.119 an early 1900s college football player practicing 00:17:37.119 --> 00:17:40.259 law to the fictional grit of characters in Point 00:17:40.259 --> 00:17:43.039 Break and Call of Duty. We saw the name applied 00:17:43.039 --> 00:17:46.579 to a Zerg unit in StarCraft II and immortalized 00:17:46.579 --> 00:17:49.380 in the music of Dr. Dre. And then we dove into 00:17:49.380 --> 00:17:52.539 the glorious Miscellany, the High Court of Australia 00:17:52.539 --> 00:17:54.960 sitting right next to a Russian children's poem. 00:17:55.660 --> 00:17:57.980 We learned the jargon of styling a horse's mane, 00:17:58.160 --> 00:18:00.480 the aerodynamics of the back edge of a sail, 00:18:00.700 --> 00:18:03.380 the fossilized shells in Portland roach stone, 00:18:03.680 --> 00:18:06.480 a traditional Native American headdress, and 00:18:06.480 --> 00:18:09.579 the butt of a marijuana cigarette. All of it. 00:18:09.579 --> 00:18:12.779 Every single piece of that sprawling mosaic contained 00:18:12.779 --> 00:18:15.220 within a single syllable. It fundamentally changes 00:18:15.220 --> 00:18:17.299 how you look at the dictionary. The source material 00:18:17.299 --> 00:18:19.880 we used today was literally just a list of links 00:18:19.880 --> 00:18:22.279 designed to stop Internet users from getting 00:18:22.279 --> 00:18:24.839 lost. It's a digital traffic cop. Exactly. But 00:18:24.839 --> 00:18:27.980 by simply pausing and reading that list, we uncovered 00:18:27.980 --> 00:18:30.039 an entire cross -section of biology, geography, 00:18:30.259 --> 00:18:32.380 culture, and highly specialized human endeavor. 00:18:32.829 --> 00:18:34.789 It has been an absolute pleasure unpacking this 00:18:34.789 --> 00:18:36.569 with you today. Thank you so much for joining 00:18:36.569 --> 00:18:39.549 us on this deep dive into the surprisingly vast 00:18:39.549 --> 00:18:42.589 world of the roach. It was a blast. And I want 00:18:42.589 --> 00:18:44.329 to leave you with a final thought to mull over 00:18:44.329 --> 00:18:47.140 as you go about your day. We spent all this time 00:18:47.140 --> 00:18:49.799 looking at how a single, seemingly ugly word 00:18:49.799 --> 00:18:52.160 can splinter into dozens of different meanings 00:18:52.160 --> 00:18:54.880 and histories. The next time you use a perfectly 00:18:54.880 --> 00:18:58.160 mundane word in conversation, ask yourself, if 00:18:58.160 --> 00:19:00.059 you were to look up its disambiguation page, 00:19:00.339 --> 00:19:03.579 what ghost towns, forgotten fish, or landmark 00:19:03.579 --> 00:19:06.140 court cases might you accidentally be invoking? 00:19:06.299 --> 00:19:08.319 It's a great reminder that no matter how unique 00:19:08.319 --> 00:19:10.599 we think our labels are, language has usually 00:19:10.599 --> 00:19:12.859 been there first. Keep questioning the words 00:19:12.859 --> 00:19:13.359 you use.
