Did you know?

Plenitude was first recorded in English during the 15th century and ultimately comes to us from "plenus," the Latin word for "full." "Plenus" has also given us "plenty," which in turn influenced a variation on "plenitude": "plentitude." Some usage commentators have objected to "plentitude," but it has been in use since the early 1600s and has appeared in the works of such writers as Henry James and Sir Walter Scott. Both words are used in the same sorts of contexts, but "plentitude" is not used as frequently as "plenitude."
