Recently a guy introduced his significant other (a female who was present) to me by saying “this is my partner”, and it took me some time (and after seeing them together) to figure out that she was a significant other instead of any other forms of “partner” - a business partner, a tennis partner, etc.
My understanding of the term is that “partner” is often used to refer to a homosexual partner, which is apparently not the case here; or, when the partner being mentioned is not present, I guess one could say “my partner and I went shopping”, in which case, the “partner” could be taken as either male or female.
But when the person herself is there, isn’t “partner” too general a term to use? would you have figured out right away that he meant a significant other? Or is this an accepted usage within any specific region? (this is in the U.S.)
