LESSON 10

Simple words are sometimes spoken of as root words. _Root_ means that

from which something grows. We know our language is a living, growing

thing and these root words are the roots where the growth begins. One

way in which this growth is accomplished and new words added to our

language is by placing syllables before or after the root word--the

simple word--as, for example: _unmanly_.

In this we have a syllable placed before and a syllable placed after the

root word _man_. The syllable placed before the root word is called the

prefix from the Latin _pre_ meaning _before_ and the Latin word to

place. Therefore, prefix means literally _to place before_.

+A prefix consists of one or more syllables placed before a word

to qualify its meaning.+

The syllable placed after the root word, or simple word, is called the

suffix, from the Latin _sub_ meaning after and the Latin word to place.

_Subfix_ the word should be literally, but for the sake of the

sound--the euphony, the good sound--we say _suffix_.

+A suffix consists of one or more syllables placed after a word to

qualify its meaning.+

+The words made by adding prefixes and suffixes are called derivative

words.+

You remember we used a suffix in forming participles. The present

participle is formed by adding the suffix _ing_ to the simple form of

the verb. The past participle is formed by adding the suffix _ed_ to the

simple form of the verb.

The words in the spelling lesson for this week are derivative words

formed by adding a prefix or suffix, or both, to the simple word. Draw a

line through the prefix and the suffix and leave the simple or root

word.
