is there a list of all words to indicate the reverse of something? Is there a term for such words?

**Examples**

* Un: unpopular (lack of popularity) / uninstall (to delete)
* Non: nonsense (making no sense)
* Less: senseless (making no sense)
* De: dehumanize / decrease

Edit: For clarification, I am not asking about antonyms. I am asking for portions of the words (eg. Un, Non, Less, De) that help indicate the opposite of something and whether there is a term for these words.

Thank you
