mindmap root((瞌睡)) sleepy applies to whatever seems about to fall asleep or to whatever leads to such a state: a ~ little town. drowsy carries a stronger implication of the heaviness or languor associated with sleepiness than of an actual need for sleep: grew ~ in the stuffy room. somnolent is likely to suggest the sluggishness or inertness accompanying sleepiness more than the actual impulse to sleep: the ~ air of a tropical noon. slumberous may replace any of the other terms; distinctively it may connote quiescence or the repose of latent powers: felt the sea's ~ power.
