au fait

My idea is, as I said before, that when he gets absolutely au fait with his donkey, it would be time enough to put him on a pony.

Next Monday—and this is Thursday—and I am by no means au fait yet in my part.

All this while we have been assuming the rider to be an accomplished horsewoman, and quite au fait at her fences.

He was not quite au fait at the needle, but got through it in time.

Marmoset crossed over walking, like a tight-rope dancer, being quite au fait at such work.
