1. Rules

You learned these rules in the fourth grade:

1. The singular possessive is formed by adding the apostrophe and s to the common form. If the word itself is long and ends in s or some similar sound, the apostrophe only is sometimes added.

2. The plural possessive is formed by adding the apostrophe only to the plural if the plural ends in s. If the plural does not end in s, both the apostrophe and s are added.

2. Exercises

1. Write the plural form after each of these words that has one: lady child.

goose Jasonn boy carpenter.

man Hercules pupil mosquito.

2. Write sentences in which you use the singular possessive of these words.

3. Write sentences in which you use the plural possessive of those words that have plural forms.
