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"?

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 "torpere," meaning "to be sluggish." What about "expedition"? Meaning both "a journey" and "promptness," it too is from "expedire."
