Unbrace → It is formed from "un-" (meaning not or opposite of) and "brace" (from Old French *bracer*, meaning to support or strengthen). The word "unbrace" means to remove support or to loosen something that is held tightly.
Think of 'un-' meaning not or to reverse, and 'brace' meaning to support. So, unbrace means to take away the support.
