Pronunciation

Forms

tú (disjunctive ti, oblique te, comitative contigo, preposed possessive determiner tu, possessive pronoun/postposed or standalone possessive determiner tuyo)[1]

Etymology

It is inherited from Latin tū (“you (singular)”), its nominative case, and has been in use since the earliest Spanish texts.[2][3][4][1] The other forms of the pronoun continue other Latin cases: te the accusative tē, and ti the dative tibi, shortened under the influence of mí.[3][5] contigo is built on the old form tigo, from tēcum (“with you”).[3][6] The possessives tu and tuyo come from the related Latin adjective tuus (“your”).[2][3]

The same Latin word is Portuguese tu, Catalan tu, French tu, Italian tu and Romanian tu.[7][1][8] In the western half of Galicia the oblique form Galician ti has taken the place of tu, which survives in Lugo and eastern Ourense.[2]

The pronoun goes back to Proto-Italic *tū.[9][1] Wiktionary takes it further to Proto-Indo-European *túh₂, the source also of English thou.[1] Coromines notes that the pronoun is common to all the Indo-European languages, from Greek to Indo-Iranian.[10]

Earliest recorded meaning

The Glosas Emilianenses already have the pronoun, and the BDELC dates its first record to about 950.[2][3] In the Cantar de mio Cid (c. 1140, in a 14th-century copy) Doña Jimena prays: „Tú, que a todos guías, val a mio Cid el Canpeador” “You who guide everyone, help my Cid the Campeador”.[11]

Semantic evolution

Tú has been in use in Spain in every period.[2] Salvá's dictionary of 1846 describes it as the form of familiar or friendly speech, and of a superior speaking to an inferior.[12] In part of the Americas it stopped being the popular form and was replaced by vos, a history that the DCECH leaves to dialectology and historical grammar; the possessives tu and tuyo stayed in use even where people say vos.[2] The DLE now describes tú as the pronoun of informal and familiar address in Spain and parts of the Americas, and also as a generic “you” that means anyone.[4]

The verb tutear “to address as tú”, first recorded in the Autoridades of 1739, was probably modelled on French tutoyer (1394); Portuguese said atuar, which was also used in Spanish.[2][3] The phrases de tú por tú “addressing each other as tú” and a tú por tú “rudely, without respect” were in the Academy's dictionary by 1869.[13]

Timeline

  • c. 950 – the first record, in the early glosses.[3][2]
  • c. 1140 – the Cantar de mio Cid uses tú in Jimena's prayer.[11]
  • c. 1180 – the Auto de los Reyes Magos: „Di, rabí, la uertad, si tú lo as sabido” “Tell the truth, rabbi, if you have known it”.[11]
  • 1256 – the pronoun in Alfonso X's prose.[14]
  • 1541 – the first record from the Americas, in Michoacán.[15]
  • 1739 – the Autoridades records the derivative tutear.[3][2]
  • 1869 – the Academy's dictionary has a tú por tú, de tú por tú and hablar o tratar de tú.[13]
  • 1899 – the Academy's dictionary gives the etymology “Del lat. tu”.[16]

Meanings

Pronoun

  1. you: the second-person singular pronoun as subject or in address, used in informal or familiar speech in Spain and parts of Latin America: Tú sabrás lo que haces.[4][1]
  2. (colloquial) A generic “you”, anyone at all: Si tú no cuidas tu salud, nadie lo hará por ti.[4]

Word family

  • tutear
  • tuteo

Usage notes

Tú is written with an accent, which distinguishes it from the possessive tu “your”, and always carries its own stress.[17] In parts of the Americas it coexists with vos.[18] De tú, with hablar or tratar, means addressing someone as tú rather than usted; the DLE marks a tú por tú as obsolete.[4][17]
