scoundrel (n.)

1580s, skowndrell, of unknown origin. One suggestion is Anglo-French escoundre (Old French escondre) "to hide, hide oneself," from Vulgar Latin *excondere, from Latin condere "to hide, put away, store," from assimilated form of com- "together" (see com-) + -dere "put," from PIE root *dhe- "to put, place." The main objection to this theory is that hundreds of years lie between the two words.
