Uncross → It is formed from "un-" (meaning not or opposite of) and "cross" (from Old English "cros", meaning to intersect or cross). The word "uncross" means to remove the crossing or intersection of something, essentially to separate or untangle.
Think of 'un-' meaning not or opposite, and 'cross' meaning to intersect. So, to 'uncross' is to separate or untangle things that are crossed.
