Moving with quick, irregular motions from side to side or up and down. The present participle of wiggle, describing continuous small movements.
From Middle English wiglen, possibly from Middle Low German or Middle Dutch wiggelen meaning 'to move back and forth.' The word developed from Germanic roots related to movement and has maintained its sense of small, quick motions since the 14th century.
Wiggling is actually a sophisticated motor skill that babies master around 3-4 months old, and it's their first step toward crawling! The word perfectly captures the essence of restless energy - notice how even saying 'wiggling' makes your tongue wiggle in your mouth.
