What's the difference between absolutely and definitely? Actually which of the following sentences is correct?
You are definitely right.
You are absolutely right.
They can mean almost the same thing, although I perceive a slight difference.
means that it is certain that you are right.
means that you are completely right. One couldn't be "more right", as it were.
So, grammatically, I'd say that in the first sentence, definitely modifies the whole sentence (the verb), whereas in the second absolutely modifies right.
When the question is about something you or somebody has a control over, it is answered with 'definitely'.
When referring to something outside one's jurisdiction, like natural laws, absoluteness can be attributed.
Here, Jim's presence has an absolute nature, that can not be influenced by anybody else's willingness to keep it one way or the other.
