from a place or position
She marched off
Try to frighten them off
away from land
The ship stood off to sea
away in space or ahead in time
She stood ten paces off
Christmas is a week off
from a course; aside
They turned off into a lay-by
into sleep or unconsciousness
I must have dozed off
so as not to be in contact or attached
He took his coat off
so as not to be attached
The handle came off
so as to be divided
a surface marked off into squares
a corner screened off
to or in a state of discontinuance or suspension
Shut off the engine
The game was rained off
The radio is off
so as to be completely finished or no longer existent
One by one they killed them off
I'm going upstairs to sleep it off
in or into a decayed state
The cream's gone off
away from an activity or function
I never take time off for lunch
offstage
Noises off
slang to a point of orgasm or ejaculation
She brought him off
take off; cut off
Off with his head!
