Did you know?

The Latin prefix com-, meaning "with, together, or jointly," is a bit of a chameleon—it has a habit of changing its appearance depending on what it's next to. For example, if the word it precedes begins with l, com- becomes col-. In the case of collaborate, com- teamed up with the verb laborare ("to labor") to form the Late Latin word collaborare ("to labor together"). Be careful not to confuse collaborate with corroborate, another com- relative. This word was formed when com- (this time shape-shifting to cor-) joined forces with the Latin word robur ("strength"). Together, by way of the Latin verb corroborare, they created the meaning "to support or help prove (a statement, theory, etc.) by providing information or evidence," which carried over into the English word corroborate.
