Simplified etymology
Somnolent comes ultimately from Latin somnus, “sleep.” Its early English meaning was “causing sleepiness,” rather than simply “sleeping.” The same root appears in insomnia, “lack of sleep,” and somnambulist, literally a sleepwalker.
Etymology
First attested in 1615. Borrowed from French somnolent, from Old French sompnolent, from Latin somnolentus, from somnus (“sleep”).
