Etymology

Origin of commence

First recorded in 1250–1300; Middle English commencen, from Anglo-French, Middle French comencer, from unrecorded Vulgar Latin cominitiāre, equivalent to Latin com- com- + initiāre “to begin”; see initiate

Explanation

Commence is a fancy way of saying "begin." Your invitation to a formal wedding might note, "The ceremony will commence at noon." If a congressman wants to start a meeting to vote on an important bill, he might say, "This meeting will begin immediately." Or, he could make the same statement in a more formal way by saying, "This meeting will commence immediately." Interestingly enough, while the word commence means to start, a commencement ceremony marks the end of a college career.
