Etymology 1

Alternative spelling of cantus. The term for “rim of a wheel” is ultimately of Gaulish origin, from Proto-Celtic *kantos (“corner, rim”). Related to Breton kant (“circle”), Old Irish cétad (“round seat”), Welsh cant (“rim, edge”).

The frequent spelling with -th- is due to the influence of unrelated (or possible Indo-European cognate) κανθός (kanthós, “corner of the eye”) (see Etymology 2), which after its borrowing became conflated with the Gaulish term for "rim" in Latin.

Noun

canthus m (genitive canthī); second declension

2. a wheel
