The term 'crossed through' can be represented by two different solutions in a crossword puzzle: XED (3 letters) and XDOUT (5 letters). XED is an informal way of saying 'crossed out, ' which is the act of drawing a line through something to indicate that it is no longer valid or relevant. XDOUT is an informal way of saying 'crossed out and thrown out, ' which is the act of crossing out something and then discarding it. Both terms refer to the same action, but the latter implies a more permanent removal.
