From the same root
Pronunciation
- /fiɾˈmaɾ/, [fiɾˈmaɾ][1]
Forms
firmar (first-person singular present firmo, first-person singular preterite firmé, past participle firmado)[1] The popular doublet hirmar “to make firm, fasten” survives in Navarre, and jirmar in Cantabria and Andalusia.[2]
Etymology
It continues inherited from Latin firmō (“to make firm, strengthen, confirm”), a derivative of firmus (“firm, stable”).[3][1][4][5] Corominas lists it among the derivatives of firme and explains why its ⟨f-⟩ did not turn into ⟨h-⟩.[6] In this word of moral meaning the pronunciation of the educated classes prevailed, helped by the heavy use of the verb and of ⟨firme⟩ “witness, guarantor” in notarial and legal language.[6] He rejects the idea that the word is a true learned borrowing.[6] Wiktionary and García de Diego do treat it as learned, a doublet of the popular hirmar.[1][2]
The same Latin verb is Portuguese firmar, Galician firmar, Catalan fermar, Occitan fermar, French fermer (“to close”) and Italian fermare.[7][8] Basque bermatu (“to guarantee”) comes from the related Navarro-Aragonese ferme (“guarantor”).[6]
De Vaan derives the Latin adjective from *fermo- and Proto-Indo-European *dʰer- (“to hold”), the root of Sanskrit and Avestan verbs meaning “to hold”.[9]
Earliest recorded meaning
Corominas's first record is in the Glosas Silenses, of the second half of the 10th century.[6][10] The early sense was “to affirm, assert”: in Berceo David lo firma esto “David affirms this”.[11] Alfonso X's prose has both “to make firm, confirm” and “to sign”.[12]
Semantic evolution
Latin “to make firm” had become “to declare on oath, conclude a treaty” in Medieval Latin.[13] In the subscriptions of charters firmare manu sua “to confirm with one's own hand” was one of the commonest formulas.[14] From confirming a document by one's signature the verb came to mean “to sign”.[4] The noun firma is recorded in a charter of 1206.[6]
Nebrija gives both firmo, fundo, stabilio and, for signing a document, subscribo.[15] Autoridades has “to sign” as the main sense, “to attest” as old, and “to prop up, make firm”.[16] The Academy's dictionary of 1817 marks the older sense as obsolete and records firmar en blanco “to sign a blank paper” and no estar para firmar “to be drunk”.[17] The reflexive “to sign oneself (with a name or title)” follows in 1869.[18]
Modern Spanish uses it for joining a team or company by contract, and colloquially firmaría por means “I would settle for”.[19][20] In Aragon it means hiring a worker or servant for a year.[19] In the Dominican Republic and Puerto Rico it means “to hire”, after English to sign on.[21][22] In Mexico it is a humorous word for urinating.[22][21][23]
