duck

We all know the image: a bird paddling on a pond. But "duck" is not just the name of an animal. As a verb, it means to lower your head or body very quickly so you do not get hit. For example, you might duck when a ball flies toward you. You might also hear that someone "ducked the question," which means they avoided answering it.

The word has an old history. It comes from the Old English dūcan, meaning "to dive" or "bend down." The bird likely got its name from this action, because it dips or dives into the water. So the animal sense and the action sense are closely linked by the idea of moving downward quickly.

The word "duck" most commonly brings to mind a waterbird—a feathered friend known for its webbed feet and fondness for ponds, lakes, and rivers. These birds are part of the Anatidae family, encompassing diverse species like mallards, teals, and canvasbacks. They are often seen "dabbling" on the surface for food or taking flight with powerful, rhythmic wingbeats.

However, "duck" also works as a verb. It means to lower your head or body quickly, usually to avoid being hit or seen. You might duck under a low branch while walking, or duck when something is thrown at you. This sense matches the idea of quick downward movement.

Figuratively, "to duck" can also mean to avoid something unpleasant, such as a duty, a problem, or a question. If someone asks you a difficult question and you change the subject, you have "ducked the question." So this word can refer to a familiar bird, a quick physical movement, or an act of avoidance. It is a simple word, but it covers several common ideas in everyday English.
