- 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,
- 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!
