Morphology

whacko = wack (semi-transparent) = wack + o

Formed by adding the informal suffix '-o' to the slang base 'wack'/'wacky'; the pattern reliably marks an eccentric person but depends on knowledge of informal slang.

Etymology

Whacko probably comes from the everyday word whack ('to hit') plus the small ending -o, or from the similar word wacky ('crazy'). A helpful way to remember it is to imagine someone a little 'hit' in the head or acting 'wacky', which is why whacko means a strange or crazy person.
