Etymology

It is inherited from Old Spanish firme, inherited from Vulgar Latin firmis, a third-declension variant of classical Latin firmus (“firm, stable, strong”).[2][3][1][4] Cornu, followed by the REW and García de Diego, explained the ending of the Spanish and Portuguese word from the Latin adverb firmē (“firmly”) instead.[5][6] Keeping the initial /f/ is irregular in Spanish, but according to Wiktionary Corominas and Pascual reject a learned borrowing.[1]

The same Latin word is Portuguese firme, Catalan ferm, Occitan ferm, French ferme, Italian fermo and Sardinian firmu;[5][6][1] Old Aragonese had fierme, and it was borrowed as Basque bermu.[5][6][1]

The Latin adjective goes back to Proto-Italic *fermos and Proto-Indo-European *dʰer-mo-s (“holding”), from the root *dʰer- (“to hold”).[7][1] De Vaan suggests that its ⟨i⟩ comes from ⟨e⟩ raised after the labial, and lists ferē, fortis, frēnum and frētus as related words.[7]

Earliest recorded meaning

The first record is the Cantar de mio Cid (c. 1140, in a 14th-century copy), where the word is an adverb: the Cid's men „firme prende(n) las posadas” “firmly take up their quarters” on the hill.[8][2] The Cortes of Benavente (1202), the first hit known from an original, use it of acts that are to stay valid: „queremos ser firmes”, “we will that they be firm”.[8]

Semantic evolution

Alfonso X's prose already has the physical sense, a stone that makes loose teeth firm, and the moral one, those who are bien firmes in the faith.[9] The legal sense “valid, binding” crossed to the Americas: a contract of 1527 in Mexico is to „vala e sea firme”.[10] In Cervantes tierra firme is the mainland as against an island, and Autoridades defines both senses of the phrase, solid ground and a continent.[11][12]

The 19th-century dictionaries added the noun: in seamanship the highest point to which a ship can heel, and the military command ¡firmes!, first in Domínguez and in Gaspar y Roig.[13][14] The Academy entered de firme and the stock-exchange en firme in 1869, and the noun for solid ground and for the gravel bed of a road in 1884.[15][16][17] In Cuba firme is virgin land, in the Dominican Republic the top of a hill, and in Chile de firme means “without moving”.[3][18][19][20] Tagalog borrowed the word as pirme.[1]
