Quite a lot of friends and acquaintances have come.

I have a nodding acquaintance with Mr Smith.

An acquaintance of mine introduced me to his closest friends.

I'm not acquainted with her.

Mr Smith is an acquaintance of hers.

At the same time you must consider that I am only a serf on this estate: that I am owner of nothing here. It is necessary therefore, that my master should be made acquainted with the business, and that we should have his consent.

Yanni was sexting with female acquaintances.

I'm delighted to make your acquaintance.

Tom is just a casual acquaintance.

He acquainted me with the change of the plan.
