In writing there are often little inline snippets to add to the meaning of the sentence - for example:

I like coffee (I am addicted).
"I swear I never seen any one so prity [sic] as Miss Daisy!"
The bold part of the examples are what I am interested in. I may not have used these all correctly, but what I'm interested in is whether or not there is a general name for these type of linguistic enhancements? Or are they all specific to themselves and thus do not necessarily belong in one set?
Note: I don't know that the tags I used for this question are necessarily the best. Feel free to edit them if you can think of better ones.
