Unsaddle → It is formed from "un-" (meaning not or opposite of) and "saddle" (from Old English "sadol", meaning a seat for riding). The word "unsaddle" means to remove the saddle from a horse, or to take away the riding seat.
Think of 'un-' meaning not or taking away, and 'saddle' being the seat for riding. So, unsaddle means to take away the saddle.
