Name
A base word is a word that can stand alone. A root word is a
word part that forms the core of a longer word. Base and root
words can be changed by adding affixes. Affixes are word parts
such as prefixes that are added to the beginnings of a word or
suffixes that are added to the end of a word. For example, the
prefix un- means “not.” The suffix -able means “able to.” When
these affixes are added to the root word bear, they form the new
word unbearable, meaning “not able to bear.”
For each word, find the root or base word. Then rewrite the word,
dividing it into its parts by drawing slashes. Underline the root or
base word.
