Freezes to is a common phrase that indicates the state of being frozen solid or stuck in one position. However, there are several antonyms that could be used to describe a situation that is the opposite of frozen solid. Unfreezes, melts, thaws, loosens, releases and softens are some of the antonyms that could be used for the word freezes to. Unfreezes denotes the action of thawing something that has become frozen while melts means to transform from a solid state to a liquid state. Thaws, on the other hand, refers to the process of unfreezing something due to high temperatures while loosens indicates the removal of something that is held tightly. Releases means to set free from a constraint or a bond while softens means to make something less rigid or hard.
