Origin & History of “needle”

Etymologically, a needle is a ‘sewing’ implement. The word comes from a prehistoric Germanic *nēthlō (source also of German nadel, Dutch naald, Swedish nål, and Danish naal), which was derived from an Indo-European base *- ‘sew’ (represented also in English nerve and neural).
