The words in Section IV express qualities. We can express three different degrees of a quality. We may say, for example, large, larger, or largest; beautiful, mare beautiful, or most beautiful. In the first case, you see, the suffixes er and est are used to show comparison; but in the second the words more and most are used.
Find three words in Section IV that you would use er and est with.
Find three words that you would use more and most with.
Try to tell. in a general way when you use er or est and when you use more or most.
3. Finding a Rule. Read these sentences:
1. She is the taller of the two girls.
2. She is the more intelligent of the two girls.
3. She is the tallest girl in school.
4. She is the most intelligent girl in school.
Do you see why taller and more intelligent are used in the first two sentences instead of tallest and most intelligent?
In comparing two things, use the suffix er or the word more; but in comparing more than two things, use the suffix est or the word most.
