Both drunk and drunken are used as modifiers before nouns naming persons: a drunk customer; a drunken merrymaker. Only drunk occurs after a linking verb: He was not drunk, just jovial. The actor was drunk with success. The modifier drunk in legal language describes a person whose blood contains more than the legally allowed percentage of alcohol: Drunk drivers go to jail. Drunken, not drunk, is almost always the form used with nouns that do not name persons: drunken arrogance; a drunken free-for-all. In such uses it normally has the sense “pertaining to, caused by, or marked by intoxication.” Drunken is also idiomatic in such expressions as drunken bum. See also drink.
