Quiz: Remember the definition of mal de mer?
"of excitement that presages death," from Old English fæge "doomed to die, fated, destines," also "timid, feeble;" and/or from Old Norse feigr, both from Proto-Germanic *faigjo- (cf. Old Saxon fegi, Old Frisian fai, Middle Dutch vege, Middle High German veige "doomed," also "timid," German feige "cowardly"), from PIE *peig- "evil-minded, hostile" (see foe). Preserved in Scottish. Sense of "displaying unearthly qualities" and "disordered in the mind (like one about to die)" led to modern ironic sense of "affected."
