chamfern.

/ˈtʃamfə/

Forms: Also 1600s chamfre.

Etymology: apparently < French chanfrein, formerly also chamfrain , chanfrain , -frin , ‘a chanfering or a channel, furrow, hollow gutter, or streake in stone-worke, etc.’ (Cotgrave), < Old French chanfraindre to chamfer v. It is possible that the French chamfrain directly gave the English chamfering n., and that from this, taken as a verbal noun, chamfer verb and noun were educed. The connection of the two senses is unexplained; sense 1 appears to be the earlier (compare chamfer v. and derivatives). (Gwilt, Archit. 928, cites sense 2 from a manuscript of 1475, but apparently in error.)

†1. A small groove, channel, gutter, furrow, such as may be cut in wood or stone. Obsolete.

chamferv.

/ˈtʃamfə/

Forms: Also 1500s chamfure, chaunfer, 1600s champher, chanfer.

Etymology: see chamfer n. Old French had chanfraindre, past participle chanfraint; modern French has chanfreiner, to chamfer. The latter element of Old French chanfraindre appears to be fraindre < Latin frangĕre to break; and the whole may be cantum frangere, chant fraindre, to break the edge or side (less likely champ fraindre to break the field).

1. transitive. To channel, flute, furrow.
