Did You Know?
Like expeditious, all of the following words contain ped. Can you guess which ones get those three letters from the same Latin root as expeditious?

encyclopedia  expedition  stampede  torpedo  orthopedic  impede

The Latin source of expeditious is the verb expedire, which means “to extricate,” “to prepare,” or “to be useful.” The ped is from pes, meaning “foot.” (The ex- means “out of,” and the literal sense of expedire is “to free the feet.”) The ped in impede also comes from pes. But the ped in encyclopedia and orthopedic is from the Greek pais, meaning “child”; stampede is from the Spanish estampar, meaning “to stamp”; and torpedo is from the Latin torpēre, meaning “to be sluggish.” What about expedition? Meaning both “a journey” and “promptness,” it is from expedire and, in turn, pes.
