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-." In the case of collaborate, com- teamed up with laborare ("to labor") to form Late Latin collaborare ("to labor together"). Colleague, collect, and collide are a few more examples of the "com-" to "col-" transformation. Other descendants of laborare in English include elaborate,- _laboratory, and labor itself.
