Notice for each pair of the above words:
•The endings –s and –es are added to many words to create the
plural form.
•The ending –es is added to words that end in sh, ch, ss, s, x, or z
to make a plural. The ending –es forms its own syllable when it
follows a consonant.
•In words that end in consonant + y, the y changes to i when
adding –es. Although the spelling changes, the vowel sound stays
the same.
Structural Analysis: Inflections: -s, -es
Look back through “The Case of the Too-Hot Apple Cider”
and “Sequoyah’s Talking Leaves” and find 6 singular
nouns. Write these in your journal. Then make each noun
a plural noun by adding –s or –es. Be ready to read each
plural noun that you wrote.
