Etymology

It is formed from Spanish por + que, the preposition with the conjunction, and Corominas records the compound from the Cantar de mio Cid on.[2][3][4][5][6] The preposition continues Vulgar Latin por, an alteration of Latin prō (“for, on behalf of”).[2][3] The conjunction is quid (“what”), which in Vulgar Latin took over the functions of classical quod and some uses of quia (“because”).[7][8]

The same compound is Catalan perquè and Italian perché.[2] The Academy's first dictionary still wrote the causal conjunction with a final accent, as Catalan and Italian do.[2][9]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) already uses it as a causal conjunction: mas, porque me vo de tierra, dóvos cincuaenta marcos “but because I am leaving the land, I give you fifty marks”.[10][2] The Auto de los Reyes Magos (c. 1180) has Porque no la auemos usada “because we have not used it”.[10]

Semantic evolution

Old Spanish used porque both for cause and for purpose: Alfonso X's Lapidario has the causal sense and por que los sabios lo entendiessen “so that the wise would understand it”.[11] Medieval texts also gave it the sense “although”, as in Berceo, and “for which reason”.[12] Terreros notes that the older language said ca in the causal sense.[13]

The interrogative por qué became a noun, porqué “reason”, recorded from the 15th century in the phrase sin porqué “without reason”; the sense “quantity, portion” follows in 1605, in the Quijote.[2][3][9] In 1869 the Academy described the interrogative as the same conjunction divided into two words with the accent on the second; its 1884 dictionary gives the two senses of the conjunction still listed today, causal and final.[14][15][16] In Andalusia porqué still means a wage, as in Nadie trabaja sin su porqué.[17]

Timeline

  • c. 1140 – the Cantar de mio Cid uses porque as a causal conjunction.[10][2]
  • 1218–1252 – a charter has it in the final sense with a subjunctive.[10]
  • 1250–1279 – Alfonso X's Lapidario uses both the causal and the final sense.[11]
  • 15th century – the noun porqué “reason”, in sin porqué.[2][3]
  • 1513 – Nebrija gives Latin cur and quare for the interrogative.[18]
  • 1516 – first record from the Americas, in Darién.[19]

Meanings

Conjunction

  1. because; for the reason that: No salimos porque hacía frío.[16][1]
  2. (with the subjunctive) So that, in order that; the same as para que: Trabajan porque a sus hijos no les falte nada.[16][1][5]

Word family

  • porque sí

Usage notes

Porque (one word, unstressed) is the conjunction;[14][1] por qué (two words, accented) asks “why?”;[14][1] porqué is the noun “reason”.[2][14][1] Moliner considers the final sense more logically written as two words, por que.[5]
