firma f (plural firmas)[1]

Etymology

It is a deverbal noun from Spanish firmar (“to sign”).[2][3][4] Corominas lists it among the derivatives of firme, dating the verb to the 10th century and the noun to 1206.[5] The verb is from Latin firmō (“to make firm, confirm”), a learned form beside the popular hirmar “to secure, fasten”.[1][6] The Latin verb is formed on firmus (“firm, stable”), from *dʰer-mo- (“holding”).[7]

The Academy noted a Medieval Latin firma from 1899 on, and Niermeyer records it in the sense of a judicial oath sworn by the claimant, formed on the verb.[8][9] Bénaben explains the sense “signature” as a firm commitment, and gives “agreement with a guarantee” for the Medieval Latin word.[10] Covarrubias and the Diccionario de Autoridades say the signature is so called because it makes firm everything written above it.[11][12]

Earliest recorded meaning

Corominas dates the word 1206.[5] DEMel lists earlier records, in the Mozarabic documents of Toledo (1159) and in the Fuero de San Sebastián (c. 1180).[13] The earliest hits in the CDH are the Latin adjective firma “firm” in Latin charters; in the Fuero de Zorita de los Canes (1218–c. 1250) firmas are the witnesses or proofs that a claimant must bring.[14][15]

Semantic evolution

In Alfonso X's General estoria the word means an oath (1272–1275) and a signature on a written agreement (1280): esta postura con sus pleytesias & sus firmas fue escripta & firmada.[16] Nebrija gives firma de escriptura as Latin subscriptio, and Percyvall's dictionary of 1591 has a firme of the hand.[17][18] Older senses were a witness who signed a deed, and a signed note by which a schoolmaster let a pupil off a beating, as in Quevedo; in Asturias the word meant a shirt collar.[15][12][19]

The Academy recorded from 1817 the Aragonese legal process called firma, one of the four procesos forales, which kept someone in possession of goods or rights, and the firma en blanco.[20][21] By 1869 it had buena and mala firma for a merchant with or without credit, and the batch of papers presented to a superior for signing.[22] The sense “business, company” is called an adapted Anglicism from firm, in the Academy's dictionary since 1984.[23] Etymonline derives English firm “business house” (1744) from German Firma and Italian firma “signature”, while Bénaben derives it from the Spanish word.[24][10]
