Did you know?

The Latin prefix com-, meaning "with, together, or jointly," is a bit of a chameleon—it has a tricky habit of changing its appearance depending on what it's next to. If the word it precedes begins with l, com- becomes col- (as in colleague, collect, and collide). In the case of collaborate, com- teamed up with laborare ("to labor") to form Late Latin collaborare ("to labor together").
