Definition

To walk with short steps, swaying from side to side like a duck or penguin. The term can refer to the gait itself or, figuratively, to move in this manner or to move slowly and heavily.

Example Usage

The toddler began to waddle across the living room, holding onto the furniture for balance.

Origin

From Middle English waden, related to 'wade,' with the -le suffix creating a frequentative verb suggesting repeated or characteristic movement.

Fun Fact

Waddling in birds like penguins and ducks is biomechanically efficient for their body structure, using less energy than walking upright would require.
