Difficulty Level: At Grade Created by: CK-12

## The Suffix -s

1. Read the twelve phrases below. Be sure you know what each one means:

\begin{align*}&\text{several}\ chairs && \text{one}\ color && \text{all the}\ plates\\ &\text{an}\ airport && \text{many}\ shows && \text{each}\ year\\ &\text{that}\ elephant && \text{three}\ uncles && \text{some}\ songs\\ &\text{both}\ sides && \text{his}\ phone && \text{all}\ mothers\end{align*}

2. Now sort the phrases into these two groups:

3. Do the italicized words that do NOT end in \begin{align*}<\text{s}>\end{align*} have the meaning “one” or do they have the meaning “more than one?”______.

4. Do the italicized words that DO end in \begin{align*}<\text{s}>\end{align*} have the meaning “one” or “more than one?” ______.

5. An element is the smallest part of a written word that adds meaning to the word.

Write the letter of the correct definition in each of the three blanks:

A suffix is ______ (a) an element that carries the basic meaning of a word and can have other elements added to it.

A base is ______ (b) a base that can stand free by itself as a word.

A free base is ______ (c) an element that goes at the end of a word and cannot stand by itself as a word.

6. Each of the italicized words that ends in \begin{align*}<\text{s}>\end{align*} has two elements: a free base and the suffix -s. For instance, chairs = chair + s

Chairs means “more than one chair.” If we take the -s away, the free base, chair means “one chair.”

Does the suffix -s add the meaning “one” or does it add the meaning “more than one”? ______

7. Here are the italicized words that end with \begin{align*}<\text{s}>\end{align*}. Analyze each one into its free base and suffix:

Word = Free Base + Suffix
chairs = chair + s
plates = +
shows = +
uncles = +
songs = +
sides = +
mothers = +
