Surface Forms

wacko positive

Morphology

wacko = wack (transparent) = wack + o

Adjectival use mirrors the noun formation: the informal suffix '-o' attached to 'wack' yields an adjective meaning crazy or absurd.

Etymology

Wacko comes from wacky 'crazy' with the slang ending -o, which makes the word sound more informal and strong. That's why calling a plan or idea wacko means it feels very 'strange' or absurd.
