chignon (plural chignons)
- Roll or twist of hair worn at the nape of the neck; a bun.
Spelled chaengnon around XIIth century with the meaning of "nape"; same Latin root as chaîne, i.e. catena, through a Late Latin form *catenione. The evolution of the meaning from "chain" to "nape" is unclear: a chain of bones (see Czech páteř for a similar evolution) or metonymical (see col, collier).
Note that, although not taken into consideration by the TLFi (see reference below), quignon could also be the etymon of chignon, considering that the same "pastry metaphor" applies to French macaron, English bun.
