Uncuff → It is formed from "un-" (meaning not or opposite of) and "cuff" (from Old French *coffe*, meaning a handcuff or shackle). The word "uncuff" means to remove or release from handcuffs or shackles.
Think of 'un-' meaning not or the opposite, and 'cuff' referring to a handcuff. So, to uncuff means to remove the handcuffs.
