There are two possible origins for
farm.
Derivation from classical Latin Some sources derive "farm" with its French version
ferme, most notably used in the context of the
Fermiers Generaux, from the mediaeval Latin
firma, meaning "a fixed agreement, contract", ultimately from the classical Latin adjective
firmus,
firma,
firmum, meaning "firm, strong, stout, steadfast, immoveable, sure, to be relied upon". The modern agricultural sense of the word stems from the same origin, in that a medieval land-"holder" (no-one "owned" land but the king himself under his
allodial title) under
feudal land tenure might let it (i.e. lease it out) under a contract as a
going concern (not as a
sub-infeudated fee), that is to say as a unit producing a revenue stream, together with its workers and livestock, for exploitation by a tenant who was licensed by the contract, or
firma, to keep all the revenue he could extract from the holding in exchange for fixed rents. Thus the rights to the revenue stream produced by the land had been farmed by the lessor. Because this was the form of the farming transaction most known to popular society, the word "farmer" became synonymous with a tenant of an agricultural holding.
Derivation from Old English According to other sources, the word
farm comes from
Middle English ferme ("farm, rent, revenue; revenue collected from a farmer; factor, stewardship, meal, feast"), from
Old English feorm, farm ("provision, stores of food, supplies, possessions; provisions supplied to the king or a lord by a tenant or vassal; rent, feast, benefit, asylum"), from
Proto-Germanic *
firmō, *firχumō ("means of living, subsistence"), from
Proto-Indo-European *
perkwu- ("life, strength, force"). It is related to other Old English words such as
feormehām ("farm"),
feormere ("purveyor, grocer"),
feormian ("to provision, sustain"), and
feorh ("life, spirit"). The Old English word is stated by these sources as having unusually been borrowed by
Medieval Latin as
firma or
ferma and to have provided the
Old French ferme "farm",
Occitan ferma "farm". This is refuted by those sources which state
firma to derive from classical Latin
firmus. The word continued the same senses of "rent, farmed office, source of revenue, feast". The meaning "rent, fixed payment", which was already present in the Old English word, was further strengthened due to the word's resemblance to the unrelated (so say these sources)
Latin firmus ("firm, solid"), and
firmitas ("security, firmness"). ==Valuation of a farm==
