Winter is the English word for the cold season — from the Old English wintru, with cognates across all Germanic languages. The name belongs to the modern wave of season-as-name choices alongside Summer and Autumn.
Winter entered the U.S. top 1000 in 1978 and has been climbing. The Gwen Stefani song "Winter" and the character Winter Ave Zoli have kept it visible. Today it sits in the U.S. top 350 and is rising.
Winter reduces to four — the number of crystalline steadiness.
