Clearance is moving your own piece off a square or line so that another of your pieces can use it, usually with a check or threat so the opponent has no time to respond.

Start0/3
White's own rook stands on a8, where the pawn wants to promote. Rh8+ clears the square with check, so Black has no time to stop a8=Q.

Sometimes the move you want is blocked by your own piece. Move that piece with check, and the square or line is free on your next move.

Questions
How is clearance different from a discovered attack?
