STAAR Blitz: Lesson One

Word Parts:
Many words are built from
smaller words, that smaller
word part is known as a
root.
The root can be the entire
word or part of a word that
is being borrowed, often
from a different language.

With a ROOT you can create many words by adding a
prefix , a suffix, or both.

Example:

Prefix Root/Base Suffix New Word

Un + Believe + Able = Unbelievable

If something is unbelievable, you are not able to
believe it.

The best way to determine the meaning of an unfamiliar word
is by breaking it apart into its word parts. Sometimes the
spelling may change.

Root or Base Word:

A Base word is a complete
word that can be used by
itself.

A Root word is a part of a
word that has its own
meaning but is not a word
on its own.

Prefix:

A Prefix is a letter or a
group of letters that are
added to the beginning of
a word that help change
its meaning.

Suffix:

A Suffix is a letter or a
group of letters that are
added to the end of a
word that help change its
meaning.
