Unbuckle → It is formed from "un-" (meaning not or opposite of) and "buckle" (from Old French *bocler*, meaning to fasten or secure). The word "unbuckle" means to undo or release something that has been fastened or secured.
Think of 'un-' meaning not or opposite, and 'buckle' meaning to fasten. So, unbuckle means to not fasten or to release something that was secured.
