Entries linking to off-season
by c. 1200 as an emphatic form of Old English of (see of), employed in the adverbial use of that word. The prepositional meaning "away from" and the adjectival sense of "farther" were not firmly fixed in this variant until 17c., but once they were they left the original of with the transferred and weakened senses of the word. Meaning "not working" is from 1861.
Off the cuff "extemporaneously, without preparation" (1938) is from the notion of speaking from notes written in haste on one's shirt cuffs. In reference to clothing, off the rack (adj.) "not tailored, not made to individual requirements, ready-made" is by 1963, on the notion of buying it from the rack of a clothing store; off the record "not to be publicly disclosed" is from 1933; off the wall "crazy" is 1968, probably from the notion of a lunatic "bouncing off the walls" or else in reference to carom shots in squash, handball, etc.
c. 1300, "a period of the year," with reference to weather or work, also "proper time, suitable occasion," from Old French seison, also saison "season, date; right moment, appropriate time" (Modern French saison) "a sowing, planting," from Latin sationem (nominative satio) "a sowing, planting," noun of action from past participle stem of serere "to sow" (from PIE root *sē- "to sow").
Sense shifted in Vulgar Latin from "act of sowing" to "time of sowing," especially "spring, regarded as the chief sowing season." In Old Provençal and Old French (and thus in English), this was extended to "season" in general. In other Indo-European languages, generic "season" (of the year) words typically are from words for "time," sometimes with a word for "year" (as in Latin tempus (anni), German Jahreszeit). Of game (as in out of season) from late 14c. Spanish estacion, Italian stagione are unrelated, being from Latin statio "station."
Meaning "time of year during which a place is most frequented" is from 1705. Season ticket is attested from 1820.
