What's the exact use and meaning of the word "literally" in English. For example in the following sentence:
The jungle literally grew tight over the buildings.
Here are some examples:
▪ The group literally poured out new ideas. [=the group produced many new ideas]
▪ Steam was literally coming out of his ears. [=he was very angry]
▪ She was literally beside herself with rage.
Are there any other words or phrases which can be used to emphasize that what you are saying is true, even though it seems exaggerated or surprising?
