Etymology

It is borrowed from Latin dēbilis (“weak, feeble; crippled”), a learned word.[2][3][4][5] Wiktionary is more cautious and calls it possibly a learned borrowing.[1] The popular outcome of the same Latin word was Old Spanish deble (“weak”), and endeble belongs to the same family.[5][1] Segura Munguía derives the latter from Vulgar Latin *indēbilis, perhaps through Old French endeble.[6]

The Latin word also gave Italian debole and the learned French débile, which French borrowed in about 1265.[7][8]

The Latin adjective is a compound of dē-: de Vaan reconstructs Proto-Italic *dē-be/oli- (“without strength”) and connects the second part with Proto-Indo-European *bel- (“strength”), the root of Sanskrit बल (bála, “strength”) and Ancient Greek βελτίων (beltíōn, “better”).[9][1] Wiktionary calls the etymology disputed, and reports an older proposal that the adjective was formed from dēbeō (“to owe”) on the model of habilis (“manageable”).[1] Lewis & Short analysed it as the prefix with that adjective, literally “unmanageable”, and Monlau and Echegaray repeated the explanation.[10][11][12]

Earliest recorded meaning

Corominas dates the word to Santillana and to Enrique de Villena, who uses the adverb débilmente, about 1433.[2][3] The CDH has earlier Castilian and Aragonese hits: in Juan Fernández de Heredia's Gran crónica de España (1385) men's menbros son debiles & enflaqueçidos por las nieues “limbs are weak and enfeebled by the snows”, and a treatise on grafting trees of 1385–1407 describes the yellowish kind as mucho debil & flaco “very weak and feeble”.[13] The sense is bodily weakness, as in Latin.[13][9] In the Glosas Silenses the Latin inbalidis is glossed debiles, aflitos, but Corominas notes that it is uncertain whether this is a record of the Romance word.[2]

Semantic evolution

In the Middle Ages, and later in popular speech, the usual word for “weak” was flaco, and débil spread slowly: it is missing from Nebrija's Spanish–Latin vocabulary and other old dictionaries, though Nebrija glossed Latin debilis as cosa feble & flaca “a feeble, thin thing”.[2][14] Covarrubias and Oudin (1607) have it, and the earliest example in the Diccionario de Autoridades is from Lope de Vega's Dorotea (1632).[2][15] Cervantes speaks of the debiles arrimos de su flaca naturaleza “the feeble props of her weak nature”.[16]

Autoridades defined it as anything thin, worn out and of little strength, and recorded an astrological use for a planet that stands in a sign with no aspect to the other planets.[15] By 1843 the Academy also used it for a person who gives way through faintness of heart.[17] Baralt (1855) warned against using it everywhere for French faible, preferring triste consuelo to débil consuelo.[18] Modern dictionaries add phonetic and chemical senses, a weak acid or base being one with a low degree of ionisation.[4][19] Débil mental names a person with a mental disability and is also an insult.[20] In Dominican Spanish débil con means having a soft spot for someone or something.[21] French débile, by contrast, now refers almost only to mental deficiency.[22]
