Wiktionary and etymonline show a different etymology for the noun wimple (which has senses including “A cloth which usually covers the head...” and “A ripple, as on the surface of water”) than Wiktionary shows for the verb wimple (which has senses including “To cover with a wimple” and “To cause ... to ripple or undulate [eg] The wind wimples the surface of water”). From Wiktionary:
Etymology 1 [noun]
From Middle English wimpel, from Old English wimpel (“veil, an article of women's dress; a covering for the neck, a cloak, a hood”), from Proto-Germanic wimpilaz (“wimple, scarf, veil”). ...
Etymology 2 [verb]
From Middle English wimplen (“to cover, conceal; to fold, drape”)
Because Middle English wimpel and wimplen are so much alike, I assume they have a common ancestor, perhaps wimpilaz, perhaps something older. What is that ancestor, if any? Is there a better and more complete etymology for the verb wimple?
