Affixes are letters or syllables added to a root word to form another word. Each is a signal word because it tells something about a word.
An affix that comes before a word or at the beginning of a word is called a prefix.
Prefixes have meanings. In the word unkind, which is the prefix? (un - means not. What is the meaning of unkind?
Another prefix which means not is in -, as in incomplete. What does incomplete mean?
Here are some words you can use to describe persons and things:

Un -
Unhappy
Unkind
Unhealthy
Unmarked
unlucky

In -
Incorrect
Inactive
Inattentive
Incomplete
inexpensive

The first syllable of the words in each group is joined by un and in. Syllables joined to the beginning of a word to change the meaning of the word. They are word prefixes. The words to which they are added are called root words.

Remember:
The un and in are syllables joined to the beginning of a word to change the meaning of the word. They are called prefixes.
Prefixes - are added to a root word.
