Pronunciation

  • /poˈsible/, [poˈsi.β̞le][1]

Forms

posible m or f (masculine and feminine plural posibles)[1] Older texts spell it possible, the usual spelling until the 18th century.[2][3]

Etymology

It is a learned borrowing borrowed from Latin possibilis (“possible”).[1][4][5] The DCECH lists it among the learned words of the family of poder, with posibilidad and imposible.[5]

The Latin adjective is formed from possum (“to be able”) and the suffix -bilis.[6][1] Quintilian says that it rendered the Greek rhetorical term Ancient Greek δυνατός (dunatós).[6][7] That verb goes back to Proto-Italic *possom, from *potis (“master, in control”) and *som (“I am”).[1]

Earliest recorded meaning

The DCECH's first record is Nebrija (c. 1495).[5] The CDH has earlier Castilian records: possible in the Libro del cavallero Cifar (1300–1305), known from a copy of the late 15th century, and posible in a translation of the Historia de Jerusalem abreviada made after 1350: „e si aquesto sea verdat o posible, dexamoslo al juizio del discreto leedor” “and whether this be true or possible, we leave to the judgement of the wise reader”.[2] Its earliest hit, of 1291, is in a Latin text.[2]

Semantic evolution

Juan Fernández de Heredia has possible in his works of 1376–1396 and 1379–1384.[2] Nebrija glossed possible as “that can be”, Latin possibilis.[8] Covarrubias in 1611 opposed it to impossible.[9]

The Diccionario de Autoridades already had the noun possible, used mostly in the plural, for a person's goods, income or means (mis possibles no alcanzan à esso), and the exclamation ¡es possible! expressing surprise.[3] In 1855 Baralt objected to the French-style use of posible after a superlative (lo menos posible), and noted that the classical writers used the noun in the singular as well as the plural.[10] The singular noun is recorded in New Granada in 1554.[11]
