Ambiamorous is an adjective used to describe someone who can enjoy being part of monogamous or polyamorous relationships.
Ambiamorous is a combination of the Latin prefix ambi, meaning both, and amorous, from the Latin amor meaning love.
The term should not be confused with biamorous. While it may seem like a synonym, much like bisexual bridges the gap between heterosexual and homosexual, biamorous means “able to love more than one person.” As such, it is a synonym for polyamorous.
