* Affix: An affix is a general term for any word part that is added to a base word to change its meaning or grammatical function. Affixes can be prefixes, suffixes, or infixes.
* Suffix: A suffix is a type of affix that is added to the end of a base word.
Here's an example:
* Base word: "Happy"
* Suffix: "-ness"
* Word with suffix: "Happiness"
In this example, "-ness" is a suffix because it is added to the end of the word "happy" to change its meaning.
Other examples of suffixes:
* -ing: (running, walking)
* -ly: (quickly, happily)
* -er: (teacher, player)
Key Point: All suffixes are affixes, but not all affixes are suffixes.
