It is unclear whether this word derives from the same etymological root as noche1. No Continental French dictionaries list this meaning as a possibility under osche. For further details, see the commentary and cognate references of noche1. It seems likely that the word is formally related to English nock and Middle English nokke. However, the earliest record of this English word listed in the MED/OED is from 1398, i.e. more than a century later than this Anglo-Norman example. The OED is uncertain about the etymology of the word nock, but suggests a Germanic context, with cognate (but later) forms in Dutch and Swedish. However, in the absence of further attestations that might contradict this, the Chant des Chanz citation suggests that the origin of this word could well be Anglo-Norman. Additionally, the implication would be that English notch and nock could both derive from the same French root, i.e. the Anglo-Norman word used to describe a small cut or incision in wood. If so, noche1 and noche2 may after all belong in one single article.
