Roots, Prefixes and Suffixes
The challenge of understanding a new word
can often be simplified by carefully
examining the word. Many words can be
divided into three parts: a root, prefix and
suffix. The root is the main part of the
word. A prefix consists of one or more
syllables placed in front of a word. The
suffix consists of one or more syllables at
the end of a word. Prefixes and suffixes
modify or add to the meaning of the root.
Not all words have prefixes and suffixes.
A knowledge of common roots, prefixes and
suffixes can give you clues to the meaning
of an unfamiliar word and help make
learning new words easier.

repeatedly in one week (like putting –logy
at the end of every RPS).
