jiggle
UK: ˈdʒɪɡ(ə)l | US: ˈdʒɪɡəl
v. to move lightly and quickly up and down or from side to side
n. a quick, light shaking movement
The word "jiggle" originates from the verb "jig," which emerged in the 16th century, meaning "to dance or move with jerky motions." The suffix "-le" is a frequentative ending in English, indicating repeated or small-scale actions (e.g., "sparkle," "dazzle"). Thus, "jiggle" evolved to describe rapid, slight movements, often playful or unsteady. The term retains its lively, rhythmic connotation, reflecting its roots in motion.
