Unlatch → It is formed from "un-" (meaning not or opposite of) and "latch" (from Old English "lætch", meaning a fastening or bolt). The word "unlatch" means to remove the fastening or bolt, effectively opening something that was closed.
Think of 'not fastening' ('un-') something that was previously secured ('latch'). This helps you remember that 'unlatch' means to open or release a fastening.
