Turned in to is a phrasal verb that refers to changing or transforming into something else. Its antonyms are untransformed, unchanged, unaltered, unconverted, remaining the same, and retaining original form. These antonyms suggest a state of consistency or continuity, indicating that the subject has not undergone any modification or alteration. For instance, a caterpillar that has not yet turned into a butterfly remains untransformed, whereas a person who has not betrayed their values remains unchanged. In contrast, when discussing metamorphosis or transformation, using terms such as transformed, changed, or evolved would be more appropriate.
