take a deep breath with the mouth wide open as sleepy or bored
"he could not suppress a yawn"
"the yawning in the audience told him it was time to stop"
"he apologized for his oscitancy"
"The child yawned during the long performance"
"the deep gaping canyon"
Now gapes the graves, and through their yawnes let loose Imprison'd spirits.

When the silent tomb shall yawn..I shall be ready for burial; not before.
Great fogs yawned beyond stone walls along the precipices.

The..writing desk..yawned open, too overflowing to close.
