: the act of gaping or yawning
Admit it: most days you greet the morn with oscitancy. In addition to referring to the act of yawning, oscitancy also refers to drowsiness (often demonstrated by yawns) as well as to general dullness or sluggishness. Oscitancy has a related adjective in the form of oscitant, which is used to describe one who is yawning with drowsiness ("the sweetly oscitant infant") or, less kindly, to one who is lazy or stupid ("an oscitant ne'er-do-well"). Both words have their origin in the Latin oscitare, meaning "to yawn," itself from the inspired combining of os ("mouth") and citare ("to put in motion").
