"by your leave"
I don't see "by your leave" phrase listed.
In back of my mind it means a polite phrase as one passes another while walking.
Any comments?
It means 'with your permission', 'with your agreement'.
Leave is an oldish word for both of these terms. It's used, or was
used, in a variety of contexts, mainly formal and often, allegedly,
at Court, if you believe the movies!
