Pronunciation

  • Brazil: /ˈfɾa.ku/[1]
  • Portugal: /ˈfɾa.ku/[1]

Forms

fraco (feminine fraca, masculine plural fracos, feminine plural fracas, diminutive fraquinho)[1] Old Galician-Portuguese wrote fraco and flaco, and the Crónica Geral also fraquo.[2][3]

Etymology

It is inherited from Latin flaccus (“flabby, drooping”), written Old Galician-Portuguese fraco and Old Galician-Portuguese flaco in the oldest texts.[2][4][5][1] Wiktionary and García de Diego treat it as a semi-learned word, as Corominas does its Spanish cognate.[1][6][7] The Latin /fl/ became /fr/, as in other Portuguese words.[2][1]

The same Latin word is Galician fraco, Spanish flaco, Catalan flac, Old French flac and Italian fiacco.[8][1] The learned flácido is from the derived Latin adjective flaccidus.[1][9]

The Latin adjective first meant “lop-eared”.[10][11] De Vaan sees in its double consonant a mark of the expressive adjectives for bodily defects and finds no etymology.[10] Wiktionary mentions a possible link with Polish błagi and Lithuanian blogas.[1]

Earliest recorded meaning

Houaiss and Cunha date the adjective to the 13th century.[2][4] In the Cantigas de Santa Maria it describes a worn-out horse, un seu palafré / fraco en que cavalgava “a weak palfrey of his that he rode”, and a traveller indo fraqu' e mui canssado “going weak and very tired”.[3] The Crónica Troiana has son ja tan flacos que non poden tomar armas “they are now so weak that they cannot take up arms”.[3]

Semantic evolution

In the Crónica Geral the word means “weak, without strength, scarce”, and is used both as an adjective and as a noun (os fracos).[3] Morais (1789) records it for a body, a wall or a voice, for a small or badly supplied army, and for weak reasoning and poor scholars.[12] Figueiredo (1899) adds the noun senses “a weak spot in a person” and “a liking, a weakness”.[13]

Today the adjective also describes weak drinks and a run-down battery.[2][14] In rural Portugal it can mean “thin”, as flaco does in Spanish.[15][7] In informal Brazilian Portuguese it has meant “consumptive”, and in Bahia “very poor”.[2][16]
