nape

The word 'nape' presents an etymological puzzle. It first appeared in Middle English around 1300, likely borrowed from the Old French hanap, meaning a drinking vessel or goblet. The semantic leap from 'cup' to 'back of the neck' is thought to be a metaphorical reference to the hollow, cuplike depression at the base of the human skull. This transition illustrates a common pattern where a concrete object lends its name to an anatomical feature based on perceived shape. Over time, the initial 'h' was lost, and the meaning specialized exclusively to denote this specific part of the neck, solidifying its place in the anatomical lexicon.

This word is a simplex form. Its origin is uncertain but likely related to Old French hanap (a goblet or cup), possibly via a transferred sense referring to the hollow at the base of the skull. Its functional role is as a single, unanalyzable lexical unit in Modern English.
