IPA: /ˈsɪzɪdʒi/
KK: /sɪˈzɪdʒi/
A term used in astronomy to describe the alignment of three celestial bodies, such as the sun, moon, and Earth, in a straight line. It can also refer to specific points in the orbits of these bodies where they are in conjunction or opposition.
During a solar eclipse, the sun, moon, and Earth are in syzygy.
Syzygy → It is derived from the Greek word "syzygia" (συζυγία), which is formed from "syn-" (meaning together) and "zygon" (meaning yoke or pair). The term originally referred to a conjunction or alignment of celestial bodies, emphasizing their coming together in a specific arrangement.
Think of celestial bodies 'coming together' ('syn-') in a 'pair' ('zygon') — that's why syzygy refers to their alignment.
