Irregular Plural Nouns
Learning to use most plural nouns in English is fairly easy. But unfortunately, some common plural nouns in English are irregular. What are these irregular plural nouns, and how can you remember them? Read on to find out!
Regular Plural Nouns
The majority of nouns in English follow the same rule to create plural nouns, and that is to add -s. For example,
A pen / Some pens
A student / Some students
This is true for all words except words that end in -ch, -sh, -s, -ss, -x, -z, and -o. With these words, we add -es. For example,
A watch / Some watches
A tomato / Some tomatoes
And when a word ends in -y, you change the -y to -i and add -es. For example,
A city / Some cities
A lady / Some ladies
