composite chart
/kəmˈpɒzɪt tʃɑːrt/
UncommonA single birth chart created by averaging two people's planetary positions, representing the relationship itself rather than either individual.
The distinction between composite charts and synastry matters to serious astrology practitioners. Composite is less common in casual conversation but carries more weight when it does come up.
