means a pleasant or dreamy state of heaviness, tiredness, and reluctance to move or exert oneself

from From Latin languor, 'faintness, weariness,' built on the verb languere, 'to be weak or droop' — a cousin of laxus ('loose, slack') and the source of words like 'languish.' It drifted into English through Old French, carrying with it the sense of a body gone soft and unhurried, the way a plant wilts in afternoon heat.
