Remember these PLURAL RULES.

Rule 1 - To form the plural of most nouns you simply add an s to the end of the noun.

Rule 2 - If the noun ends in sh, ch, x, s, or z add es to make it plural.

Rule 3 - If a noun ends in a consonant plus y, the y changes to i before es is added. Note: If the noun ends in a vowel plus y, just add s.

Rule 4 - Most of the words that end with f, ff, or fe are made plural by changing the ending to -ves.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In this lesson you will learn two additional plural rules.

Rule 5 - Words that end in o are usually made plural by adding s.

There are exceptions that must be memorized or looked up.

There are two helpful rules:

1. All words that end in a vowel plus o (ao, eo, io, oo, uo) have plurals that end in just s.
2. All musical terms ending in o have plural ending in just s.

A few nouns ending in o have two plural forms.

Practice - Write the plural form in the blank after each word.

Rule 6 - Some words are the same in both the singular and the plural forms.
