languor

the word 'languor' entered english in the 14th century via old french from the latin verb 'languēre', meaning to be faint, weak, or droop. the latin root itself is likely connected to a proto-indo-european base suggesting slackness or looseness. the suffix '-or', a common latin agent or state noun ending, transforms the verbal concept into a noun denoting the condition of being weak or faint. over time, the english meaning softened from a state of illness or listlessness to often describe a pleasant, dreamy weariness or a tranquil atmosphere of inactivity.
