Vaughn Smith on Life as a Hyperpolyglot

Vaughn Smith, a Washington-area carpet cleaner who took no language classes and became a hyperpolyglot anyway, talks with Tyler Cowen about how the skill actually works from the inside — what he can do, what he can’t explain, and where the questions outrun his own understanding of himself. The conversation stays close to his testimony throughout, resisting both the urge to marvel at the number of languages and the urge to dress up one man’s practice as a theory of language acquisition.

Key ideas

1. The numbers are self-reported and slippery. Smith puts himself at roughly ten languages he has dreamed in, a beginner’s grasp of about 36, and fluency in about eight. He offers no fixed test for any of these categories — ‘fluent’ and ‘beginner’ are his own impressionistic labels, not benchmarked against an external standard.
2. The path was organic, not engineered. He grew up bilingual (English and Spanish, through his mother’s family in Orizaba, Mexico), then added French at 11 and German at 13 entirely on his own initiative — no school programme drove any of it. He names 15, on leaving junior high, as the point he decided language learning would be ‘his thing’.
3. His method is immersion and listening, not classroom study. He has never taken a language class. Every fluent language was acquired by living or working among speakers, and he explicitly tells learners to front-load listening and avoid cramming vocabulary. He also names spaced repetition — deliberate, spaced review — as how he commits new words to long-term memory.
4. Speech comes first; writing follows from pronunciation. For Nahuatl specifically, he says the spoken language is more fundamental to his learning than the written form, and that once he has the sounds, the Latin-alphabet spelling used for Nahuatl gives him little trouble.
5. Retention feels like slow retrieval, not relearning. Describing a conversation in Latvian after fifteen years of disuse, he compares recall to ‘a slow computer rebooting’ — the words are still there, but surfacing them takes time, and that time shortens the more the language gets used again.
6. He reports thinking differently in different languages but cannot explain how. Asked directly how switching languages changes his thoughts, he answers ‘I don’t know’ and falls back on a concrete example — cursing in Slovak — rather than a mechanism. He has not read Chomsky on structural linguistics and does not know the Sapir-Whorf hypothesis by name, even though his own testimony (cursing in the language of the people he learned it from, feeling like a different person in different languages) sits close to what that hypothesis describes.
7. Language loss is a live concern, tied to dignity rather than only preservation. Discussing indigenous languages in and around Orizaba and Oaxaca state, Mexico, he links language survival to how speakers see themselves — an outsider’s visible interest in a minority language, he reports, measurably lifts how local children regard their own.

How many languages, and what ‘having’ one means

Cowen opens on numbers, and Smith gives several different figures depending on the question: about ten languages he has dreamed in, roughly 36 with at least a beginner’s grasp, and about eight he calls fluent. He never defines these thresholds, and the interview does not press him to. The clearest thing he does establish is a hierarchy within his own learning: speech is primary. Asked whether the written form or the spoken form is more fundamental to how he learns a language, he answers ‘Spoken’, and says he moves to reading only afterwards. For Nahuatl specifically, he says writing it is not difficult once he knows the sounds, because the modern Latin-alphabet orthography imposed after the Spanish conquest maps closely onto pronunciation — ‘if I go by pronunciation, then I can write pretty much anything.’ Where he does not know a word, he says so directly, rather than folding the gap into an inflated overall count.

An organic, self-directed apprenticeship

Smith’s account of his own origin is unglamorous. He grew up bilingual in English and Spanish because his mother, from Orizaba in Veracruz state, Mexico, took the family there and spoke Spanish with them. Around 11 he took up French on his own, prompted by his mother’s own materials and enthusiasm for the language; around 13, still with no school direction, he started German. Nobody made him take language classes — he states this twice, unprompted. He locates the turning point precisely: leaving Alice Deal Junior High School for Wilson High School, at around 15, is when he decided this would be ‘his thing’ — reinforced, he says, by peers remarking on his pronunciation and his speed at memorising vocabulary.

Method: immersion, listening, and no classroom

No fluent language in Smith’s account was learned in a classroom. Czech and Slovak came from a job as caretaker at the grounds of the Central and Eastern European Art Foundation, where he worked daily alongside Táňa and Dušan Pavelkovi, a couple from eastern Slovakia; the same job let him brush up Bulgarian and pick up Romanian and Serbian from co-workers. Finnish came from a girlfriend who taught him. Nahuatl came from a distant cousin, a professor of the language, in the village of Rafael Delgado near Orizaba, where Smith spends part of each year. Welsh came from the Duolingo app, which he calls useful but slow. Russian started as a teenager listening — not translating — to cassette tapes of Russian rock bands a school friend gave him, guessing unfamiliar words from context until roughly half the vocabulary of a song was enough to infer the rest. Asked directly for teaching advice, he says: ‘Don’t cram so much vocabulary into one little session. Mix it up: some writing, some reading, but a lot of listening. People learn by listening.’ For retaining new vocabulary long-term he names spaced repetition explicitly. What makes a language hard for him is grammar, not sound or script — he names Hungarian’s case system and irregular verb forms as the hardest thing he has studied, and contrasts it with Norwegian’s almost invariant verb forms, which he calls easy. Complex writing systems such as Chinese characters he treats as a separate, secondary difficulty, purely a matter of volume to memorise.

Retention over time: recall as a slow reboot, not relearning

Smith offers a concrete test of his own retention. In front of the Latvian embassy in Washington, D.C., he found himself conversing in Latvian after not having spoken it for more than fifteen years; some words came slowly, others — the ones he ‘knew too well’ — came instantly. A similar encounter in Bulgarian, after about ten years of disuse, came back noticeably faster. His own model for this: ‘It’s just a matter of putting myself in the place of the language, and it’s like a slow computer rebooting information, bringing it to the forefront, so it’s ready for use.’ The claim is retrieval speed, not storage loss — nothing in his account suggests the languages themselves degrade, only that surfacing them takes longer the less recently they were used.

Where the mechanism runs out

This is the section where Cowen presses hardest and Smith’s answers thin out. Asked whether he thinks different thoughts in different languages, he says yes without hesitation. Asked how that operates, he says: ‘I don’t know.’ What follows is not an account of mechanism but a single anecdote — he curses in Slovak when someone cuts him off in traffic, a habit he traces to daily life among hot-tempered eastern Slovak friends, and one that surfaces even in Mexico, unconnected to any Slovak speaker being present. Later in the conversation he offers a more general, and more speculative, description of the same phenomenon: ‘There’s a soul to the language. It’s like you’re starting to become this new miniature other-person version of yourself when you use that language.’ Pressed on the theoretical vocabulary that would formalise either claim, he has nothing to offer: asked about Chomsky on structural linguistics, he says ‘I have not read the book’; asked directly about the Sapir-Whorf hypothesis — the academic name for something close to what he has just described — he says ‘I’m not familiar with it.’ The honest reading is not that Smith holds a theory of linguistic relativity; it is that he has a strong, repeated first-person experience that language-switching changes something about his mental state, reported without any framework for explaining why, and without contact with the literature that argues about it.

The day job, and the one that actually used his languages

Cowen asks whether cleaning carpets — work that presumably leaves the mind free — helps his language learning the way a more demanding profession might not. Smith rejects the premise outright: ‘there’s nothing rewarding about carpet cleaning that’s conducive to learning languages at all.’ He works for his brother’s carpet-cleaning business in the Washington, D.C. area; the closest thing to an occupational use of his languages is the occasional customer — Latvian, Finnish, Norwegian, an Irish-Gaelic speaker he has served three times — who is startled to be addressed in their own language mid-job. The job he calls most rewarding for language use is an earlier one: caretaker at the Central and Eastern European Art Foundation, where he spoke Czech, Slovak, Bulgarian, Romanian, and Serbian daily with colleagues. He also spent roughly a year, around 2000, as a roadie for the punk band The Goons, driving their van between Washington, D.C., New York, and Hartford, Connecticut — a period he defends as formative rather than wasted.

Language, dignity, and loss

Smith treats language loss as a live and personal concern, not an abstraction. He estimates around fifteen distinct indigenous languages in Oaxaca state alone, and describes younger speakers there shifting to Spanish or English even as some communities actively work to preserve their languages through bilingual schooling. He reports a specific, repeated effect of his own presence: learning Nahuatl in Rafael Delgado as a visible outsider — ‘even though I’m half Mexican, to them I’m an outsider’ — prompted local children to see their own language as something worth an outsider’s effort, which he describes as a direct lift to how they valued it themselves. He extends the same logic to immigrant families in the United States, telling customers who speak languages other than English at home to keep speaking those languages to their children rather than fearing it will crowd out English: ‘Teach your child your language… There will be no problem with her learning English.‘
