Morphology

insomniac = insomnia (transparent) = insomnia + ac

Formed from the noun 'insomnia' with the adjective/person-forming suffix '-ac', so the meaning 'a person suffering from insomnia' is directly derived.

Etymology

Insomniac comes from Latin parts in- 'not' and somnus 'sleep', and it shares the same root as insomnia. So an insomniac is someone who 'does not sleep', which explains why we use the word for a person who has trouble sleeping.
