Surface Forms

knucklehead singular
knuckleheads plural

Morphology

knucklehead = knuckle + head (semi-transparent) = knuckle + head

The components 'knuckle' and 'head' are clear, but the overall insult meaning 'a foolish person' is idiomatic and not strictly predictable from the parts.

Etymology

Knucklehead is a playful insult made from knuckle ('the hard joint of a finger') and head ('the part where you think'). It pictures someone whose head is hard like a knuckle, so calling someone a knucklehead means they are acting like a fool.
