Etymology
The word "insomniac" is a modern English formation built from classical components. Its core is the Latin root somnus, meaning "sleep", which traces back to the Proto-Indo-European root swep-no-, also the source of "somnolent" and "soporific". This root is prefixed with the Latin negative "in-", creating the sense of "without sleep". The suffix "-iac", adapted from Greek via Latin, attaches to indicate a person characterized by that condition. Thus, the literal construction "not-sleep-person" logically evolved into the modern term for someone who suffers from chronic sleeplessness.
