PRACTICE
Ask a volunteer to read aloud each rule. Have students read the examples given and supply examples of their own. Remind students that there are exceptions to these rules. Encourage students to consult a dictionary if they are unsure. Point out that in compound nouns, the principal word is the person, place, or thing that is being modified by the other words. In the examples, brother and editor are being modified by in-law and in-chief.
EXERCISE 1 When students have completed the exercise, have them tell which rule for forming plurals applies for each word.
