In comparison statements, you can use "even" or "much" (or "a lot") to emphasize the degree of the adjective or adverb.
However, is there any difference between "even", "much", an "a lot"?
For example:
I can swim faster than he.
I can swim even faster than he.
I can swim a lot faster than he.
I can swim much faster than he.
What is the difference?
