"Not only on the contrary" is a commonly used associative phrase that is often used to indicate the opposite or unexpected situation. Here's an example of using "not only instead" to form a sentence:
Instead of failing as expected, she successfully completed her mission.
In this sentence, "not only" means a turning point, and "instead" means an unexpected situation. The meaning of the whole sentence is that she behaved the opposite of what was expected, because not only did she not fail, but she succeeded in completing the task.
In addition, it is possible to use the phrase "not just instead" to express more complex situations. For example:
Instead of giving up because of failure, he worked harder to pursue his goals.
In this sentence, the words "not only" are used together with "on the contrary" to emphasize the positive attitude and determination he showed in the face of difficulties. He behaved differently from many because he didn't give up because of failure and instead worked harder to pursue his goals.
In conclusion, "not only instead" is a very useful associative phrase that can be used to express the opposite or unexpected situation. When forming sentences, you can choose the appropriate usage according to the context and the needs of the expression.
