Etymology
The word in the sense of an agricultural land-holding derives from the verb "
to farm" a revenue source, whether taxes, customs, rents of a group of manors or simply to hold an individual manor by the
feudal land tenure
Under the English feudal system several different forms of land tenure existed, each effectively a contract with differing rights and duties attached thereto. Such tenures could be either free-hold, signifying that they were hereditable or perpet ...
of "fee farm". The word is from the medieval Latin noun ''firma'', also the source of the French word ''ferme'', meaning a fixed agreement, contract, from the classical Latin adjective ''firmus'' meaning strong, stout, firm. As in the medieval age virtually all manors were engaged in the business of agriculture, which was their principal revenue source, so to hold a manor by the tenure of "fee farm" became synonymous with the practice of agriculture itself.
