From Middle English gossomer, gosesomer, gossummer (attested since around 1300, and only in reference to webs or other light things), usually thought to derive from gos (“goose”) + somer (“summer”)^[1] and to have initially referred to a period of warm weather in late autumn when geese were eaten^[2][3][4][5] — compare Middle Scots goesomer, goe-summer (“summery weather in late autumn; St Martin's summer”)^[1] and dialectal English go-harvest,^[6] both later connected in folk-etymology to go)^[5][7][8] — and to have been transferred to cobwebs because they were frequent then or because they were likened to goose-down.^[2][3][5][4] Skeat says that in Craven the webs were called summer-goose, and compares Scots and dialectal English use of summer-colt in reference to "exhalations seen rising from the ground in hot weather".^[9] Weekley notes that both the webs and the weather have fantastical names in most European languages:^[10] compare German Altweibersommer (“Indian summer; cobwebs, gossamer”, literally “old wives' summer”) and other terms listed there.
