Forms

quien (relative pronoun, plural quienes or (proscribed, when not modifying a verb) quien)[1] Old Spanish also had qui, from the Latin nominative, which was in general use until the 13th century (the Cid, Berceo, Apolonio, Alexandre) and still appears in El conde Lucanor.[2] Quien was invariable in the Middle Ages; the plural quienes is first found in the first half of the 16th century and was still resisted in the 17th.[2][3]

Etymology

It is inherited from Latin quem, the accusative of the interrogative pronoun quis (“who?”), which was treated as a stressed word.[2][3][1] The unstressed relative que comes from the same accusative, which lost its final consonant in proclitic position and did not diphthongise.[2] The DLE describes the Latin form as the accusative of the relative quī.[4] The same accusative is Portuguese quem.[5]

The Latin pronoun goes back to *kʷis and Proto-Indo-European *kʷis, whose accusative was *kʷim.[6][1]

Earliest recorded meaning

Corominas dates the first record to the earliest texts, the Glosas Emilianenses; the BDELC dates it to about 950.[2][3] The Cantar de mio Cid uses quien as a relative, both as subject and object, and as an interrogative.[7]

Semantic evolution

Alfonso X's prose already has the three uses of the word: relative, interrogative and indefinite (non era quin ge los partisse “there was nobody to share it among them”).[8] Since quien had no plural, Golden Age writers used it with plural antecedents;[9] Cervantes wrote a quien for a quienes.[9] Autoridades still called it an adjective, “the same as cual”, used mostly in questions, and gave the distributive use quién se fue a su casa, quién a la plaza.[10][11]

The Academy's 1869 dictionary was the first to call it a relative pronoun.[12] Modern grammar restricts the relative quien to persons, and allows it without a preposition only in explanatory clauses.[4][13] The compound quienquiera (Nebrija) continues Old Spanish quienquier (Juan Ruiz).[2]

Timeline

  • c. 950 – first record, in the Glosas Emilianenses.[2][3]
  • c. 1140 – the Cantar de mio Cid uses it as relative and interrogative.[7]
  • 1250–1279 – Alfonso X's Lapidario has the relative por quien.[8]
  • c. 1495 – Nebrija gives Latin quis and qui, quae, quod.[14]
  • first half of the 16th century – the plural quienes appears.[2]
  • 1726–1739 – Autoridades defines it as an adjective equivalent to cual.[10]
  • 1869 – the Academy classes it as a relative pronoun.[12]
  • 1917 – Alemany gives the etymology from quem, the accusative of qui.[15]

Usage notes

Written with an accent, quién is the interrogative and exclamative pronoun (¿Quién llama?, ¡Quién lo hubiera dicho!), and in the formula quién… quién it means “some… others”.[16][13] Set phrases include quien más, quien menos “everyone to some extent” and cada quien “each one”.[4][1]
