The antonym for the phrase "torn in to" is "intact." Unlike the former word, the latter means that something remains whole or complete without any damage or tear. For instance, if someone says, "The package arrived intact," it means that the package was not tampered with, and its contents remain in their original state. Similarly, if a person states that their clothes are intact after a strenuous workout, it implies that their clothes did not rip or tear. The word "intact" can also refer to something that is untouched or unaltered. In essence, "torn in to" and "intact" are antonyms because they are opposite in meaning.
