Word Origin and History for apoplexy



late 14c., "sudden fit of paralysis and dizziness," from Old French apoplexie or directly from Late Latin apoplexia, from Greek apoplexia, from apoplessein "to strike down and incapacitate," from apo- "off" (see apo-), in this case probably an intensive prefix, + plessein "hit" (cf. plague (n.), also with a root sense of "stricken"). The Latin translation, sideratio, means "disease caused by a constellation."
