Moving unsteadily from side to side, or appearing unstable and likely to fall.
From Middle Low German 'wabbeln' or similar Germanic roots meaning 'to wave' or 'to move unsteadily.' The word entered English in the 17th century and has maintained its onomatopoetic quality, where the sound mimics the meaning of uneven, rhythmic movement.
Wobbling is almost onomatopoeia—say the word out loud and you can almost feel the unsteady motion in your mouth! This connection between how words sound and what they mean is called 'sound symbolism,' and linguists have found that words with 'w' and 'o' sounds are disproportionately used for unstable, uncertain movements across many languages.
