Unlace → It is formed from "un-" (meaning not or to reverse) and "lace" (from Old French *lacier*, meaning to fasten or tie). The word "unlace" means to reverse the action of fastening or tying something, specifically by loosening laces.
Think of 'un-' meaning to reverse and 'lace' meaning to tie. So, unlace means to reverse the tying action.
