Etymology tree
From the same root
Pronunciation
- /impoˈsible/, [ĩm.poˈsi.β̞le][1]
Forms
imposible m or f (masculine and feminine plural imposibles)[1] Medieval spellings include jnposyble, inposible and jmpossible;[2][3][4] Covarrubias and Autoridades still write impossible.[2][3][4]
Etymology
It is borrowed from Latin impossibilis (“impossible”), one of the learned words of the family of poder.[5][6][7][1] The Latin adjective is formed from in- (“not”) and possibilis (“possible”), which in turn is formed from Latin possum (“to be able”) + -bilis.[8][9][10] The Diccionario de Autoridades explained it as a Spanish compound of the negative prefix and posible.[4]
Corominas dates the word to 1438, in the Corbacho, earlier than the 1495 he gives for the simple adjective.[6][5] The DEMel and the CDH have earlier records, in Alfonso X's Siete Partidas and in a text of 1293.[11][2]
Earliest recorded meaning
The DEMel gives the singular and the plural from Alfonso X's Siete Partidas (1256–1265).[11] The earliest CDH hit is in the Castigos of 1293, quoting Saint Gregory: jnposyble [cosa] es que dios non sea misericordioso “it is impossible that God should not be merciful”.[2]
Semantic evolution
From the start the word meant “that cannot be or be done”.[2] Covarrubias (1611) notes that it is sometimes used for something merely very difficult, and the Academy's dictionary of 1869 adds the noun use, as in “to ask for an impossible thing”.[3][12] The sense “unbearable, intolerable”, said of a person, was recorded by Alemany in 1917; the Academy's 1884 edition added the rhetorical figure.[13][14] In Chile and parts of the Americas it also means “very dirty, untidy”.[15][16]
