notch: [16] Not much is known for certain about the word notch, apart from the fact that its immediate source, Anglo-Norman noche, existed at least a couple of centuries before English acquired it. There may well be some connection with Old French oche ‘groove, notch’ (probable source of the English darts term oche ‘line where the dart-thrower stands’); the initial n could well have arisen by misdivision of a preceding indefinite article (as happened with nickname).
