Yes,you are right, but in my experience with Japanese teachers they usually say Aite(partner) when referring to uke ...
jup. My experience too.
"aite" means just "partner" as Willi states.
And it also means "the antagonist" or "the other one of a pair of two".
So this meaning is a little bit nearer to the common understanding of "uke".
Like using "shite" it's more about the roles of both partners.
