Describing something that moves in a circular or spiral way.
The gyratory motion of the planets around the sun is a fundamental concept in astronomy.
Gyratory → It is formed from "gyrate" (from Latin "gyrari", meaning to turn or spin) and the suffix "-ory" (meaning relating to or characterized by). The word "gyratory" refers to something that is characterized by turning or spinning motion.
Think of something that is 'turning' ('gyrate') and 'relating to' ('-ory') — that's why gyratory means relating to a turning motion.
