Linguist Answers Word Origin Questions | Tech Support | WIRED

This video explores etymology and historical linguistics, showing how everyday words carry surprising histories shaped by sound changes, semantic drift, borrowing, and human creativity. It highlights examples like “gossip” originally meaning “godparent,” “but” shifting from “outside” to its modern contrastive use, and “orange” traveling from Sanskrit through Arabic and Spanish into English. The piece also explains how rebracketing errors created words like “apron” and “adder,” how taboo euphemisms gave rise to terms like “pee” and “poop,” and how regular sound changes, such as those described by Grimm’s law and the Great Vowel Shift, transformed pronunciation over centuries. Ultimately, the video emphasizes that language change is constant and natural, with generational slang complaints being an age-old pattern, while reconstruction of ancient languages reaches limits beyond a few tens of thousands of years.

• ▶ 0:10 Etymology is the study of word origins and meaning changes; it is a branch of historical linguistics that reveals surprising histories hidden in everyday words, like “gossip” originally meaning “godparent.”
• ▶ 1:14 Word meanings shift over time, sometimes becoming more or less gender-neutral: “bro” broadened from “brother,” while “man” narrowed from a general word for people to a male-specific term.
• ▶ 3:47 English’s oddities and euphemisms come from real historical forces: silent letters often reflect older pronunciations or Latin influence, and words like “unalive” or even “bear” show how taboo avoidance drives language change.
• ▶ 4:56 Grimm’s law describes regular sound changes in Germanic languages—e.g., Latin “P” became English “F” (piscis→fish) and Latin “C” became English “H” (canis→hound), caused by articulatory slips.
• ▶ 6:25 New words often arise through euphemism for taboo subjects, like imitating the sound of urination to create “piss,” then replacing it with the letter “P” (“pee”) when it felt too blunt.
• ▶ 8:04 Semantic drift changes meanings over time: the word “but” originally meant “outside,” then shifted to “without,” then “except,” and finally became the modern contrastive “but.”
• ▶ 8:49 Languages have likely existed for at least 100,000 years, but it is unknown whether all vocal languages share a single common ancestor.
• ▶ 9:09 Most European and many Asian languages derive from Proto-Indo-European, spoken by nomadic pastoralists on the Pontic-Caspian Steppe about 6,000 years ago; its vocabulary reveals aspects of their daily life.
• ▶ 11:37 Linguists can reconstruct ancient languages like Proto-Indo-European and Proto-Afroasiatic, but beyond roughly 17,000 years the noise-to-signal ratio makes further reconstruction impossible.
• ▶ 12:36 New words can arise by naming unfamiliar animals after the sounds they make, like calling a cat-like creature “mew” or “meow.”
• ▶ 13:23 Words like “mama,” “papa,” and “dada” come from babies’ babbling, which parents eagerly interpret as referring to themselves.
• ▶ 13:45 Even after a language has an established word, such as “father,” new babbling-based forms like “dada” and “daddy” keep being reinvented generation after generation.
• ▶ 14:04 The word “orange” entered English via a long borrowing chain: French from Spanish, Spanish from Arabic, and Arabic ultimately from Sanskrit.
• ▶ 14:17 A key linguistic shift involved rebracketing: the Spanish word for orange began with “N,” and English speakers reinterpreted “a naran” as “an orange,” moving the “n” to the article.
• ▶ 14:31 The same false division created “apron” from “napron” and “adder” from an earlier word beginning with “n” — showing how mistakes can birth new words.
• ▶ 14:38 Language mistakes can give birth to new word forms, like "snake n" being reinterpreted as "an Adder."
• ▶ 14:52 The word "poop" probably originally meant something like "fart," based on an onomatopoeic "po" sound meaning "puff."
• ▶ 15:04 "Poop" later started being used euphemistically to refer to other things that come out of your butt, giving it its modern meaning.
• ▶ 15:23 The original English word for the season was "harvest," not "fall" or "autumn" – it is related to German "Herbst."
• ▶ 15:39 By the 16th century, both "fall" and "autumn" were already used in Britain to refer to the season.
• ▶ 15:07 "Fall" is not an American invention or corruption of "autumn"; it simply comes from the phrase "fall of the leaves."
• ▶ 15:49 "Autumn" is a borrowing from Latin via French, showing everyday words can have surprising histories.
• ▶ 15:57 "Demure" dates back to Middle English, likely from French meaning "mature," and is cognate with "mature."
• ▶ 16:14 The TikTok revival of "very demure, very mindful" exemplifies playful, ironic language use that gets a reaction.
• ▶ 16:32 A commenter joking about being an older person confused by new slang cites examples like “YNS,” “FOMO,” and text abbreviations such as “C’s” for “cuz” and “T’s” for “that.”
• ▶ 16:47 The linguist’s key takeaway: this generational complaint about “kids these days” and their slang is not new—it happens in every generation.
• [16:47–16:51] The linguist begins to argue that adults feeling disconnected from younger generations’ language is a recurring, normal part of language change that has likely happened for as long as people have been speaking.
• ▶ 16:52 Language change is driven partly by younger speakers not wanting to sound like the previous generation, which is why slang constantly emerges.
• ▶ 17:02 Slang rarely survives in ancient written records because most surviving texts are formal writing; notable exceptions include sexual slang in ancient graffiti.
• ▶ 17:33 The Latin dictionary word for "head" was caput, but modern Romance languages use descendants of testa — originally meaning "potshard" — extended from "skull" to "head," showing humble words can replace older formal terms.
• ▶ 18:00 The origin of the word “no” is unknown, but it traces back to Proto-Indo-European.
• ▶ 18:07 The English word “no” is a shortened form of an earlier phrase meaning “not one.”
• ▶ 18:20 One proposed origin is that the root may come from the facial expression babies make when refusing something.
• ▶ 18:45 Vowel sounds are produced by shaping the vocal tract with the lips, tongue, and teeth as air passes from the lungs through the larynx.
• ▶ 19:08 The Great Vowel Shift began around the late 14th century; for example, the vowel in “bite” moved higher and closer to the front of the mouth, eventually becoming a diphthong and creating the modern contrast with “beet.”
• ▶ 19:42 The shift was not an isolated change but a chain reaction that reshaped how multiple long vowels (such as those in “boat,” “boot,” and “bout”) were pronounced in English.
• ▶ 19:56 Shakespeare didn’t invent as many words as people think — other contemporary writers had similar or larger vocabularies, and dictionary compilers often found words in his works first simply because they used his texts as sources.
• ▶ 20:10 Being the first person to write a word down is not the same as inventing it; Shakespeare often gets credit just for being the earliest recorded instance.
• ▶ 20:19 Shakespeare did contribute memorable expressions like “one fell swoop,” and some words that look invented, such as “mockable,” were actually assembled from existing, productive English building blocks.
• ▶ 20:35 English originally used "thou/thee" for one person and "you" for more than one, but the plural "you" crept in as a respectful way to address a single person, and by the 17th century "thou/thee" was largely dropped—partly because groups like the Quakers used it for everyone and made it unpopular.
• ▶ 22:19 "Pregnant" etymologically means "before giving birth" (pre- "before" + Latin nasci "give birth"), and it shares a surprising family connection with "embarrassed," since Spanish embarazada traces back to an Arabic word for "rope," shifting from "tangled in a rope" to "entangled/inconvenienced" and then becoming a euphemism for pregnancy.
• ▶ 23:25 The word "dog" has no known root—it simply appeared in late medieval English—and it belongs to a mysterious set of words (dog, pig, hog, frog) with the playful "-cga" ending, suggesting these were expressive, nursery-style words rarely written down in formal texts.
