't is a bitter pill to swallow that this the origin of this word:
rancor
early 13c., from O.Fr. rancor, from L. rancorem "rancidness, grudge, bitterness," from L. rancere "to stink" (see rancid).

is attributed to my Old Frisian ancestors. It does not look O.Fr. to me and I doubt if the Old Romans ever made it to the Frisian regions at all. Their heavy armour must have got stuck in mud and peat. It'll get a strikethrough in my dictionary at once. A bodacious act.
