Irregular Plural Nouns
Most nouns are changed from their singlar forms to their plural forms by adding an -s or an -es. For example: bird/birds, beach/beaches. Some nouns, however, are made plural in other ways, such as by changing their spelling. For example: tooth/teeth. Some nouns have the same singular and plural forms. For example: sheep/sheep, fish/fish. Plural nouns that are made by one of these other methods are called irregular plural nouns.
