plenipotentiary

There was no American plenipotentiary empowered to make any political compact with the Islanders.

A day or two after the new plenipotentiary had set out on his mission, he received a touching letter from his master.

He appears as it were the latter's unacknowledged representative ashore, a plenipotentiary without credentials.

None but the like-minded can come plenipotentiary to our court.

So far, we have alluded only to the instructions prepared before plenipotentiary departure.
