Unit 11 - Plural Nouns

Grammar

1. Plural Nouns

-s ending - Plurals are generally made by adding -s to the noun. For example:
Cat - cats, tree - trees, building - buildings.

There are a number of exceptions to this rule, here are some of the most common ones. 

-es ending: Nouns ending with -o, -s, -x, -z, -ch, and -sh usually add -es to the noun. For example:
tomatoes, dresses, foxes, quizzes, watches, stashes.

- ies ending: Nouns ending with a consonant + -y usually replace the -y with -ies. For example:
country - countries, party - parties.

- ves ending: Some nouns ending in -f replace the -f with -ves. For example:
wife - wives, knife - knives, elf - elves.

As always, memorizing these rules is probably less helpful and much less interesting than exposing yourself to real English usage and learning them at the same time. Time for some more exercises!
