Here's why:
* Base word: A base word is the fundamental part of a word to which affixes (prefixes and suffixes) can be added to create related words.
For example:
* Base word: "happy"
* Prefix: "un-"
* Suffix: "-ness"
These affixes can be added to the base word "happy" to create related words:
* Unhappy: (prefix added)
* Happiness: (suffix added)
