It's often used to emphasize the intensity or magnitude of something, and it conveys a sense of awe or wonder.
Here are some examples:
* "He was tremendously successful in his career." (This implies that his success was exceptionally great).
* "The food was tremendously delicious." (This suggests that the food was incredibly flavorful).
* "The children were tremendously excited about the trip." (This means they were extremely happy and enthusiastic).
It's important to note that "tremendously" is a rather strong word, so use it sparingly to avoid overusing it.
