Relating to or affected by coma; characterized by unconsciousness or deep sleep.
From coma (Greek kōma, 'deep sleep') + -anic (suffix forming adjectives). The Greek root originally referred to lethargy or unconsciousness in medical contexts.
The word 'coma' comes from the same Greek root as 'comic' in some ancient texts, but they diverged dramatically—one means sleeping and one means funny! Medical terminology borrowed heavily from Greek because ancient physicians needed precise terms for conditions they observed.
