Origin

English synastry is an astrological term coming ultimately from Greek synastría, a noun compounded of the Greek preposition and prefix syn, syn- “with,” completely naturalized in English, the Greek noun ástro(n) “star,” familiar in astronomy, astronaut, and astrology, and the abstract noun suffix -ia, which is also native to Latin, becoming the noun suffix -y in English. Synastry entered English in the 17th century.
