Morphology

nutso = nuts (semi-transparent) = nuts + o

The word is built from the colloquial adjective 'nuts' plus a slangy '-o' ending, so the crazy-person meaning is fairly easy to recover but still informal and lexicalized.

Etymology

Nutso as a noun comes from nut ('a crazy person') with the added -so, so a nutso is someone seen as wild or unpredictable and the word is very informal.
