Category talk:Terms derived from Anglo-Norman

Guidelines
Is there any logic over when to use this and when to use Category:Old French derivations? I can understand for as it's more similar to the Norman spelling  than the 'Parisian' spelling. But for, why would that be here? Since the Norman and the Parisian spellings are both bastard:, why is this considered to be from Anglo-Norman rather than from Old French? I personally only tend to use Anglo-Norman derivations when the spelling is typically 'Norman' (see Appendix:Anglo-Norman spellings). --Mglovesfun (talk) 16:51, 20 May 2011 (UTC)
