What is an "affix"?
An affix is a morpheme that is attached to a base word or root to modify its meaning or create a new word. Affixes can be added to the beginning of a word, known as a prefix, or to the end, known as a suffix. There are also infixes, which are inserted within a word, and circumfixes, which are added around a word. For example, in the word "unhappiness", the prefix "un-" and the suffix "-ness" are both affixes that alter the meaning of the root word "happy". Affixes are essential for word formation and help expand vocabulary in many languages.
