Definition of polyamory in US English:



  • The philosophy or state of being in love or romantically involved with more than one person at the same time.

    • ‘Just as with sexual orientation, polyamory is a way of life that you cannot easily deny if it is meant for you.’
    • ‘People who practice polyamory are entitled to the same respect as those who are monogamists.’
    • ‘It is very likely that the next person one is attracted to has no concept of polyamory, and expects to enter into an exclusive relationship, not an open one.’
    • ‘Swinging, bisexuality, homosexuality, polyamory, etc, are all ‘alternative lifestyles’.’
    • ‘In my experience it is men, more often than women, that are unfamiliar with true polyamory, where communication and consent are a given.’


1990s: from poly- ‘many’ + Latin amor ‘love’.
