firma f (plural firme)[1]

Etymology

It is from Italian firmare (“to sign”), a back-formation: a noun made from the verb with no suffix.[2][3][4][1] The verb is a learned word, borrowed from Latin firmō (“to make firm, confirm”), from firmus (“firm, steady”); the popular outcome of the same Latin verb is fermare.[2][3][1]

The Latin adjective goes back to Proto-Italic *fermo-, from Proto-Indo-European *dʰer- (“to hold”), and is related to Sanskrit धर्म (dhárma, “support, law”).[5][1]

Earliest recorded meaning

DELI's first record is in Michelangelo Buonarroti the Younger (1618), with a signature that gives force to laws and decrees.[2][6] The GDLI has an older firma “confirmation, formal pledge”, from the late 13th or early 14th century.[7]

Semantic evolution

In the 19th century the word gained the sense of the act of signing (1869–1876).[2] The army gave fare or mettere la firma, to sign on for longer service (1931), and the firmaiolo who did so;[2] mettere la firma then came to mean to accept something gladly.[2] From the 1950s a firma is also a well-known writer or journalist, after the magazine Le grandi firme, and later a famous fashion house or designer.[2][4][8]

Italian firma spread to the languages of Europe: German Firma “signature” is recorded from 1733 and then meant a business, the sense English firm has had since 1744 after an earlier sense “signature” (1574).[7][6] French firme (1877) came from English or German, and DEI notes that the word reached the Middle East.[9][6]
