Surface Forms

lunatic positive

Morphology

lunatic = lunar (semi-transparent) = luna + ic

The form links to 'lunar'/'luna' so learners familiar with 'lunar' or 'moon' may guess a moon-related meaning, but 'luna-' is not a productive standalone English morpheme.

Etymology

Lunatic comes from the Latin word luna 'moon'. People long ago thought the moon's phases could make someone 'mad', so the word once meant someone 'affected with insanity', especially during a full moon.
