The term 'clear the board' is often used in a variety of contexts, such as in board games or in business meetings. In this context, it means to ERASE all items from the board, which can be done by using the solutions ERASE (5 letters), BUS (3 letters), RID (3 letters), and UNPEG (5 letters). Erasing the board would involve wiping away any writing or objects that are on the board, while BUS, RID, and UNPEG could refer to removing any pieces or markers that are on the board.
