anadear

A literary verb meaning to waddle — to walk with a side-to-side gait like a duck (ánade), typically describing someone whose walk is affected by weight, a limp, or exaggerated swaying. It's a vivid but uncommon word, more likely met in descriptive prose than everyday speech.

• El pato anadeaba torpemente hacia el estanque. — The duck waddled clumsily toward the pond.
• El anciano anadeaba apoyado en su bastón. — The old man waddled along, leaning on his cane.
• Anadeaba con el peso de las bolsas de la compra. — She waddled under the weight of the shopping bags.

Assuming anadear is common everyday vocabulary — it's a literary, descriptive word; most speakers would just say caminar torpemente or moverse como un pato.
