- migraine (n.)
- late 14c., megrim, from Old French migraigne (13c.), from vulgar pronunciation of Late Latin hemicrania "pain in one side of the head, headache," from Greek hemikrania, from hemi- "half" + kranion "skull" (see cranium). The Middle English form was re-spelled 1777 on the French model. Related: Migrainous.
