A non-gendered adjective for one's partner in a relationship based on
polyamory or
non-monogamy. It is used in place of boyfriend, girlfriend, wife, husband, and even partner, to show that you are taken, but not exclusively.
It can be used in conjunction with "primary" or "
secondary" just as you would one of the previous alternatives.
"My polymate and
I are going on a
vacation together soon. We've been together for 16 months now."
"Oh, that's awesome. I hope the two of you have fun. Are you bringing your
other girlfriend?"
