c.1300, “a period of the year,” with reference to weather or work, also “proper time, suitable occasion,” from Old French seison, 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” (see sow (v.)).
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” (e.g. Latin tempus (anni), German Jahrzeit).
1781, from French nuance ”slight difference, shade of color” (17c.), from nuer ”to shade,” from nue ”cloud,” from Gallo-Roman *nuba, from Latin nubes ”a cloud, mist, vapor,” from PIE *sneudh- ”fog” (cf. Avestan snaoda ”clouds,” Latin obnubere ”to veil,” Welsh nudd ”fog,” Greek nython, in Hesychius “dark, dusky”). According to Klein, a reference to “the different colors of the clouds.”
