Regional Spanish slang: tío, guay, che, vaina, chido

Five slang words tell you roughly where a Spanish speaker is from. Tío ("guy", "mate") and guay ("cool") are colloquial Spanish from Spain; che ("hey", "mate") is Argentina, Uruguay, Paraguay and Bolivia; vaina ("thing", "whatsit") is Venezuela, Colombia and much of the Caribbean and Central America; and chido ("cool", "great") is Mexico. In 423 million words of Spanish film and television subtitles, tío is the most frequent of them by a long way — though part of that is uncles — and chido the rarest. This page takes each word in turn, with its meaning, an example and a count, then adds seven more regional words that the Spanish academies' dictionaries also place on the map.

How the words were placed and counted

Where a word belongs comes from the dictionaries, not from the counts. The Real Academia Española's Diccionario de la lengua española marks a sense with the countries that use it — coloq. Esp. means "colloquial, Spain"; Méx. means Mexico. The academies' Diccionario de americanismos does the same for words of Spanish-speaking America. Where neither marks a country, this page says so and names the source that does.

The counts are from a frequency list of Spanish subtitles, and two things limit what they can say:

• The list does not say where a film was subtitled. Spanish subtitles from Spain and from Latin America are mixed together in one list, so a count says how often a word appears in Spanish subtitles as a whole. It never says how often Spaniards, Mexicans or Argentines use it, and nothing below should be read that way.
• A count is a count of a spelling. Where a word has an ordinary meaning as well as its slang one — vaina is also a pea pod — the figure covers both, and is marked as a ceiling: the slang use is lower, sometimes much lower.

Tío and tía (Spain): "guy", "mate" — and uncle

Tío is first of all "uncle", and tía "aunt". The Academy's dictionary then lists colloquial senses: a person you are saying something good or bad about (¡Qué tía más lista!, "What a clever woman!"), a person whose name you don't know or won't say (Nos recibió un tío, "Some guy met us"), and a form of address for a friend or companion. The Academy gives these senses no country mark; Wiktionary labels both the "guy" and the "mate" senses as Spain.

The subtitles say tío 302 times per million words, which makes it number 334 of all Spanish words. How much of that is uncles? The count cannot separate the senses, but the other subtitle lists give a yardstick, because films in every language mention uncles:

If Spanish subtitles mention uncles about as often as the others do, then more than half of every tío — something like 150 per million — is the "guy, mate" word. Tía shows the same thing much more faintly: 86 per million against 59 to 80 for "aunt" in the other languages, so its "girl, woman" sense is a smaller share.

Guay (Spain): "cool", "great"

The dictionary marks guay coloq. Esp. — colloquial, Spain — as an adjective meaning "very good" and an adverb meaning "very well". (An unrelated guay, an old poetic word for "alas", is marked as no longer in use.)

It is said 17.99 times per million subtitle words, number 3,914 in the list.

Che (Argentina, Uruguay, Paraguay, Bolivia): "hey", "mate"

Che is an interjection to call someone, stop them or get their attention, or to show surprise. The Academy marks it for Argentina, Bolivia, Paraguay and Uruguay, and for Valencia in Spain; the Diccionario de americanismos describes it as a word for asking something of someone you are on familiar terms with. It is also where Ernesto "Che" Guevara's nickname came from: he got it for using the word so often.

The subtitles say it 4.88 times per million — a ceiling, since the count also takes in the name Che and the name of the letter ch.

Vaina (Venezuela, Colombia and the Caribbean): "thing", "whatsit"

In general Spanish a vaina is a sheath for a blade or a pea pod. In much of Latin America it is also a thing or matter you can't name, don't remember the name of, or would rather not mention — a whatsit. The Academy marks that sense for Colombia, Cuba, Ecuador, Guatemala, Honduras, Nicaragua, Panama, Peru, Puerto Rico and Venezuela. The Diccionario de americanismos lists it in more countries still, labels the sense vulgar in Venezuela, and records a separate, vulgar sense in El Salvador — so it is not a word to borrow casually.

Vaina appears 2.12 times per million words, a ceiling that includes every sheath and pod.

Chido (Mexico): "cool", "great"

The Academy marks chido coloq. Méx.: colloquial, Mexico, meaning "pretty, nice" and "very good". It is Mexico's guay — the dictionary even lists guay among its synonyms.

It is the rarest of the five on screen: 0.21 times per million, number 74,046. Guay turns up about 84 times as often. That is a fact about this subtitle list, and the list cannot say why — it does not record which films were subtitled in which country.

Seven more words with a country attached

Each of these has a country mark in one of the academies' two dictionaries. The counts are for the masculine form; chavala, piba and cuata are the feminines.

Two of them need care. Güey is two words in one: the Academy's dictionary has only "a stupid person", and the Diccionario de americanismos adds "inseparable friend, companion" for Mexico, along with a dismissive "some guy". Between friends it is "dude"; to a stranger it can be an insult. It is also spelt wey, which adds another 0.20 per million. And chaval is the Spain partner of pibe: both mean "kid", and chaval is said about eleven times as often in these subtitles.

Which of these should a learner use?

Recognise all of them; use them only where they belong. A Spanish learner who calls a Mexican friend tío or tells an Argentine something is chido sounds like someone who learned from a mixture of films — which is what this subtitle list is. Spain also has its own "OK": vale is measured against the borrowed word in OK in other languages.

The neutral words always work: chico or chica for a young person, amigo for a friend, genial or muy bueno for "great", cosa for "thing", trabajo for "job". Amigo, trabajo and cosa are all in the 1,000 most common Spanish words, and the two-minute Spanish vocabulary test shows how many you know already.

Verbavia (our own course) builds its Spanish course on that frequency list, so the words every Spanish speaker uses come before any one country's. It is free on the web in any browser, including on a phone, with grammar explained in English and hand-written lessons. Regional differences in everyday objects rather than slang — coche and carro, ordenador and computadora — are in how many words are there in Spanish; the words English took from Spanish are in Spanish words used in English; and France's slang, built partly by turning words back to front, is in French slang you will actually hear.

Spanish swear words, set beside those of seven other languages, are in the most common swear word in each language.
