Unfreeze → It is formed from "un-" (meaning not or opposite of) and "freeze" (from Old English "freosan", meaning to become frozen or to congeal). The word "unfreeze" means to reverse the process of freezing, or to make something not frozen.
Think of 'un-' meaning not or the opposite, and 'freeze' meaning to become solid due to cold. This helps you remember that 'unfreeze' means to make something not frozen.
