A podiatrist is a foot doctor. Got a bunion? A hammer toe? Call the podiatrist.
The word podiatrist is composed of two ancient Greek parts: pod, meaning "foot," and iatrist, meaning "healer." Other kinds of doctors have a similar suffix: think psychiatrist — a doctor of the mind. The pod prefix and suffix is used to name a number of things. For example, a camera tripod has three "feet." Pea pods and iPods? Nothing to do with feet!
