Etymology

It is inherited from Vulgar Latin firmis, the Vulgar Latin form of Latin firmus (“firm, solid, strong”), written Old Galician-Portuguese firme in the oldest texts.[2][3][4][1] The Vulgar Latin adjective of the third declension, with its ending ⟨-is⟩, explains the final ⟨-e⟩ of the Portuguese and Spanish word.[5][6][7] Nascentes also mentions an archaic Old Galician-Portuguese fermo, the form kept in enfermo.[8]

Spanish firme has the same origin, while Italian fermo, French ferme and Occitan ferm continue the classical adjective; the REW sets the Spanish and Portuguese forms apart in brackets.[9][6][10]

The Latin adjective goes back to Proto-Italic *fermos and Proto-Indo-European *dʰer-mo- (“holding”), from the root Proto-Indo-European *dʰer- (“to hold”), and is related to Sanskrit धर्म (dharma).[11][1] De Vaan suggests that the ⟨i⟩ of the Latin word comes from an older ⟨e⟩ raised after the labial.[11]

Earliest recorded meaning

Lorenzo's chronology finds the word in Galician-Portuguese charters from 1255: a testator wishes que este meu testamento que seya firme e stavil “that this my testament be firm and stable”, and in 1259 a lease remana firme “remains binding”.[4] The first sense was thus legal validity, beside the physical and moral steadiness of the Cantigas de Santa Maria (se nos firme creermos “if we believe firmly”, firm’esperança “firm hope”).[4]

Semantic evolution

The Crónica Troiana uses firme of a resolute, constant hero, and the cantigas have the adverbial phrase a firmes “firmly”.[4][12] Bluteau in 1712 separates the physical sense, of walls and doors that cannot easily be shaken, from the senses “fixed, stable” and “constant”.[13] Morais in 1789 records terra firme, the inland country as opposed to the sea, and canto firme, plainchant.[14][15] Figueiredo in 1899 has the financial sense, of loans and public funds bought or sold at a fixed term.[16] Modern dictionaries add a fast colour that does not fade, settled weather, and in Brazil the noun firme, high dry ground among flooded forest.[2][17]
