Surface Forms

nutcase singular
nutcases plural

Morphology

nutcase = nut + case (semi-transparent) = nut + case

Formed by combining 'nut' (slang for a crazy or obsessed person) + 'case' (informal 'instance/person'); both components are colloquial, so understanding depends on slang knowledge.

Etymology

Nutcase joins nut (slang for 'crazy') and case (a 'person in a certain state'). It gives the simple picture of someone's 'head' being a 'nut', which is why it is an informal name for a person who acts very strangely or may be dangerous.
