1. Literally, of sailors, to prepare for something (such as a battle) by removing or securing objects on the deck of a ship. That enemy ship is getting too close—clear the deck!

2. By extension, to cease doing something in preparation for a more important task or happening. I know you're busy with that paperwork, but clear the decks—I've got a big client coming in this afternoon.

3. To flee hastily; to depart quickly Uh oh, here comes mean old Mr. Jerome. Clear the decks, everyone! The staff cleared the decks when they saw the boss asking for volunteers to work on the weekend.
