Irregular plural nouns

Many English nouns have irregular plural forms. While the general rule says that adding -s or -es to a noun forms its plural, this is not always true. The following examples show some of the ways English nouns become plural.


For some nouns, like fish, there is no difference between the singular form and the plural form. Sometimes, however, people do use regular plural endings for irregular nouns, so in casual conversation you may hear fishes or elks. 

One fish; three fish

A deer; many deer

An elk; some elk

One species; several species

A series; many series

Some English words come from Latin, and take a Latinate plural ending.


A syllabus; all of the syllabi

A larva; many larvae

This genus; these genera

Her thesis; their theses

One crisis; two crises

An index; a couple of indices

A matrix; two matrices

Sometimes nouns end in -f or -fe and the f becomes a v before adding -s or -es.

A loaf of bread; a few loaves of bread

One wolf; a pack of wolves

A knife; some knives

Some plurals have no pattern and have to be memorized.

That person; those people

نکته: در موتون رسمی و حقوقی از (persons) استفاده می کنیم، برای تفکیک بین چند فرد و یا گروهی از افراد. 

One child; three children

One mouse; two mice

A goose; several geese

A man; two men

An ox; a pair of oxen

Some nouns do not have plural forms because they cannot be counted. These are called noncount nouns, or mass nouns. Some common noncount nouns are water, rice, sand, butter, mud, rain, advice, homework, progress, and music.


Here is a full list of some the most common irregular plural nouns in English:


Child/Children

Man/Men

Woman/Women

Person/People

Persons is often used in formal, legal contexts to emphasize individuals as opposed to a group. People is the plural of person that's most commonly used in everyday communication to simply refer to multiple humans. But people can also be used as a singular noun to refer to a population or particular community.

Mouse/Mice

Goose/Geese

Foot/Feet

Tooth/Teeth

Fungus/Fungi

Cactus/Cacti

Sheep/Sheep

Fish/Fish

Deer/Deer

Moose/Moose

Crisis/Crises

Irregular plural nouns examples in sentences

Here are some examples of irregular plural nouns used in sentences:


There were two mice scurrying around the kitchen.

Both children were playing in the park.

She saw a herd of deer in the forest.

The men were discussing the issue.

He saw a flock of geese flying in the sky.

The people of the town gathered for the meeting.

There were several cacti in the garden.

Rules of irregular plurals

Although there are no hard rules for forming irregular plural nouns, there are some patterns that can help you remember them.


Some nouns just change one letter, such as 'man' to ‘men,’ or ‘woman’ to 'women.'

Some nouns change their spelling completely, such as 'mouse' to 'mice'.

Some nouns use the same form in both singular and plural, such as 'sheep' and 'fish'.

Some nouns have a different ending depending on their origin, such as 'fungus' to 'fungi'.

Once you find and remember enough of these words, you will be able to remember the correct plural form of most irregular nouns based on these patterns.


Common mistakes

One of the most common mistakes that English learners make with irregular plural nouns is confusing them with regular nouns. The plural of 'man' is 'men' and not 'mans'. Similarly, the plural of 'woman' is 'women' and not 'womans'.


Similarly, the plural of 'person' is 'people' and not 'persons' although this form sometimes comes up when we refer to a number of individuals. Remember that some nouns share the same form in both singular and plural, such as 'sheep' and 'fish'.

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
