oscit-
(Latin: yawning, the act of yawning; to gape [see the definitions for these words below])
From os, "mouth".
Yawning may appear as a psychoneurotic symptom. For instance, one neurasthenic patient related that he had troublesome spells of yawning at times of anxious expectation; such as, when he was waiting for an important appointment.
In other neurotics, frequent yawning may indicate the patients' inability to concentrate, which they struggle to overcome. In hysteria, spasms of yawning may have the same significance as convulsive laughter or crying as an expressive movement.
Irresistible yawning spells were known to early clinicians as oscedo or chasmodia. Yawning may be used in social intercourse as a subtle expression of aggressive tendencies, implying that a partner is a bore.

6. Etymology: Yawn ultimately goes back to the Indo-European base ghei-, ghi-, which also produced Greek khaskein, "gape"; a close relative of English chasm and Latin hiare, "gape, yawn"; source of English hiatus.
Involuntary opening of the mouth, which is often caused by suggestion. Yawning is characterized by breathing first inward, then outward. Repeated yawning is often a sign of drowsiness. It may also sometimes be a sign of depression.
