Question

Which word part is added to an affix to make a new word?

Answer 1

The word part added to an affix to create a new word is typically called a "root" or "base." An affix, which can be a prefix (added to the beginning) or a suffix (added to the end), modifies the meaning of the root to form a new word. For example, in the word "happy," "happi-" is the root, and by adding the suffix "-ness," we get "happiness."
