An archaic verb meaning to curse or place a curse upon someone; to damn.
From Old English acursian or Middle English accurse, composed of a- (intensive prefix) plus curse. This shows how English doubled up prefixes for emphasis in earlier centuries.
Medieval people loved adding 'a-' to the front of verbs to make them sound more intense—'accurse' sounds much more serious than just 'curse,' which is probably why fantasy writers still use words like 'accursed'!
