... for a farce is that in poetry which grotesque is in a picture. The persons and action of a farce are all unnatural, and the manners false, that is, inconsisting with the characters of mankind. [Dryden, "A Parallel of Poetry and Painting"]
According to OED and other sources, the pseudo-Latin farsia was applied 13c. in France and England to praise phrases inserted into liturgical formulae (for example between kyrie and eleison) at the principal festivals, then in Old French farce was extended to the impromptu buffoonery among actors that was a feature of religious stage plays. Generalized sense of "a ridiculous sham" is from 1690s in English.

fare (n.)youdaoicibaDictYouDict
Old English fær "journey, road, passage, expedition," from strong neuter of faran "to journey" (see fare (v.)); merged with faru "journey, expedition, companions, baggage," strong fem. of faran. Original sense is obsolete, except in compounds (wayfarer, sea-faring, etc.) Meaning "food provided" is c. 1200 (Old English also had the word in the sense "means of subsistence"); that of "conveyance" appears in Scottish early 15c. and led to sense of "payment for passage" (1510s). Meaning "person conveyed in a vehicle" is from 1560s.
fare (v.)youdaoicibaDictYouDict
Old English faran "to journey, set forth, go, travel, wander, make one's way," also "be, happen, exist; be in a particular condition," from Proto-Germanic *faran "to go" (cognates: Old Saxon, Old High German, Gothic faran, Old Norse and Old Frisian fara, Dutch varen, German fahren), from PIE *por- "going, passage," from root *per- (2) "to lead, pass over" (see port (n.1)). Related: Fared; faring.

farinaceous (adj.)youdaoicibaDictYouDict

farm (n.)youdaoicibaDictYouDict
c. 1300, "fixed payment (usually in exchange for taxes collected, etc.), fixed rent," from Old French ferme "a rent, lease" (13c.), from Medieval Latin firma "fixed payment," from Latin firmare "to fix, settle, confirm, strengthen," from firmus "firm" (see firm (adj.)).

Sense of "tract of leased land" is first recorded early 14c.; that of "cultivated land" (leased or not) is 1520s. A word of confused history, but there is agreement that "the purely agricultural sense is comparatively modern" [Century Dictionary]. There is a set of Old English words that appear to be related in sound and sense; if these, too, are from Latin it would be a very early borrowing. Some books strenuously defend a theory that the Anglo-Saxon words are original (perhaps related to feorh "life").

Phrase buy the farm "die in battle," is at least from World War II, perhaps a cynical reference to the draftee's dream of getting out of the war and going home, in many cases to a peaceful farmstead. But fetch the farm is prisoner slang from at least 1879 for "get sent to the infirmary," with reference to the better diet and lighter duties there.
