Forms

ferme (plural fermes)[4] The Old French masculine ferm disappeared before the 14th century, replaced by the feminine form ferme.[2][5][1]

Etymology

The adjective is inherited from Latin firmus (“solid, firm; steadfast, reliable”).[6][2][5][1][7] Rey calls “firmus” of obscure origin, Wiktionary and Littré relate it to an Indo-European root “*dʰer-” “to hold”.[2][4][8] “Ferme”, at first only the feminine, took the place of the masculine “ferm” in the 13th century.[5][6]

Compare Italian fermo, Old Occitan ferm, Spanish firme and Portuguese firme.[5][8]

Earliest recorded meaning

Geffrei Gaimar's Estoire des Engleis (about 1140) uses the feminine ferme for “solid”; the adverb ferm “solidly” is in Marie de France (about 1180).[6][2]

Semantic evolution

Figuratively it meant “sure, steadfast” in the Roman d'Eneas (about 1160).[6][2] The Châtelain de Coucy has Tant ai en li ferm assis mon corage.[8] Terre ferme, the mainland, is old, and for Venice it named its mainland territory.[8][9] The adverb is used for “firmly” and, in the 20th century, “hard, a lot”: travailler ferme, discuter ferme.[2] In commerce a vente ferme is final, and at the Stock Exchange des fermes were firm deals (Balzac).[9][10] As an interjection, ferme ! urges courage.[1]

Forms

ferme f (plural fermes)[4]

Etymology

The farm is a deverbal noun from Old French fermer (“to make firm, fix, settle”), formed in Old French in the legal sense of the verb.[2][5] The Grand Robert takes it instead from the adjective ferme1: a “rente à ferme” was an agreement for a fixed payment.[1] Medieval Latin “firma” “lease, farm” is found in England from 1100, Wiktionary takes the word from it, mentioning a debated link with Old English feorm (“provisions, rent”), while Littré derived “firma” from Latin firmus.[2][4][8]

Earliest recorded meaning

About 1160–75 rente à ferme is a legal agreement by which land is let for a fixed rent.[2][1]

Semantic evolution

By metonymy it named the rural estate so let (1539), and then any farm and its buildings.[2] Under the Ancien Régime it also meant an agreement to collect a right or tax (1481), as in the Ferme générale set up by Colbert, whose fermiers généraux (1690) collected indirect taxes.[2] Apart from law and farming, the usual sense today is the farmhouse with its buildings.[2] Fermier “tenant of a right” (1207) and “farmer” (1282) followed the same path, and fermette (1941) names a small farm made into a country house.[2]

  • c. 1160–75 – Rente à ferme.[2][1]
  • c. 1170 – Affermer.[2]
  • 1207 – Fermier, tenant of a right.[2]
  • 1367 – Fermage.[2]
  • 1481 – The farming of a tax.[2]
  • 1539 – A rural estate.[2]
  • 1941 – Fermette.[2]

Meanings

Noun

  2. (law) A lease of farmland for a fixed rent, donner à ferme.[2][11]
  3. (historical) The farming of taxes: la Ferme générale.[2]
  4. By extension, an installation of many units: ferme éolienne, a wind farm.[11]

Usage notes

A third ferme, a roof truss, is recorded in 1690 and comes from fermer in the old sense “to fix”; in the theatre it also names a piece of scenery mounted on a frame (1752).[3][6]
