Etymology

The origin is disputed.[1] It is, according to the DMLBS and Niermeyer, borrowed from Old English feorm (“food, provision, feast”);[2][3] Niermeyer and Köbler add that its sense was influenced by firmus (“firm, fixed”) and firmō (“to make firm, confirm”).[2][3][4] The MLW instead derives it from that verb,[5] as does Etymonline, for which it is a “fixed payment”.[6] If it is from Old English, it is related to feorh (“life”).[1] Through Old French ferme (“rent, lease”) it is the source of English farm.[6]

Earliest recorded meaning

Its first dated use is in an English charter of about 945 (known from a 13th-century copy), where two villages must feed a monastic community for three days or pay prō firmā instead.[2]

Semantic evolution

In England it first meant a food-rent, provisions owed for a set number of days or nights, and a feast or banquet.[2][3] Niermeyer adds compulsory hospitality, and then the lease at a fixed rent, a farmed office or other source of revenue, and a farmed manor.[3] Continental charters use it for a rent or lease (ad firmam) and for the leased estate.[5] Etymonline takes the English word farm from the sense “fixed payment”.[6]

Timeline

  • c. 945 – An English charter allows a payment prō firmā instead of food.[2]
  • 1012–1018 – Thietmar of Merseburg uses it for an oath.[5][4]
  • 1205/16 – A Westphalian charter has a tithe taken ad firmam, at rent.[5]
  • c. 1300 – English farm, “fixed payment”, comes from it through Old French.[6]

Meanings

Noun

  1. (Medieval Latin) A food-rent, provisions owed for a set period.[2]
  2. (Medieval Latin) A banquet, feast; compulsory hospitality.[3][2]
  3. (Medieval Latin) A farm, lease at a fixed rent; the rent itself.[3][5][1]
  4. (Medieval Latin) A farmed office or source of revenue; a farmed manor.[3][5]

Usage notes

Niermeyer gives the judicial oath as a separate word, derived from firmō.[3] Köbler also records a firma “cage for young hawks”, from Old French.[4]
