The word 'wicker' entered English from Scandinavian languages, such as Old Swedish viker, meaning "willow." This term is traced back to the Proto-Germanic root wik-, which conveyed the sense of "to bend" or "to turn." This etymological connection is deeply logical, as willow branches are famously flexible and were the primary material for weaving pliant baskets and furniture. Thus, the modern abstract meaning for woven plant material directly evolved from the ancient root describing the essential physical property—bendability—of the source plant.

This word is a simplex. It is a loanword from a Scandinavian source (e.g., Old Swedish viker "willow") into Middle English (wiker). Its ultimate origin is from a Proto-Germanic root related to bending or turning, linked to the pliability of the willow branches used in weaving.
