pods

"Pod" and "ped" are confusing little sets of letters. They often have to do with feet. A biped is a two-footed animal. A podiatrist is a foot doctor. A tripod is a three-legged object used to support something. The pedals on your bike are where your feet go.

But sometimes they don't have anything to do with feet. A pediatrician is a children's doctor (whether the child has feet or not). A pod is what peas come in. Pedantic means academic (sort of).

So what's the deal?
