Although this is not confused with another similar word, it is constantly misused. Literally means exactly as described. Somebody who is 'literally bursting with pride' is actually exploding. When someone is 'bursting with pride' they are figuratively doing so. It is usually best not to use the word at all, but in academic writing you should only use it when there may be confusion between whether what you are describing was a literal or figurative occurrence, or when you are drawing attention to a phrase that is usually misused:
It was literally hot enough to fry an egg on the pavement as can be seen in Figure 1.
When vasovagal syncope occurs, people can literally pass out with surprise.
