Singular and Plural Nouns

To identify things we refer to them with different names.

These things could be any random things.

It could be somebody’s name.

It could be a place.

It could be an animal.

It could be a thing.

Or it could even be a feeling.

So, based on what they represent, these nouns have been classified into different types.

What makes nouns interesting is that the same noun can be used in various forms.

Just like a normal playground which can be used to play both cricket and football.

Similarly, nouns too can be used in different forms.

The two different forms of nouns are: SINGULAR and PLURAL

A singular noun is used when we refer to a single thing or person.

On the other hand, a plural noun is used when we refer to more than one thing.

Interestingly, a singular noun itself can be changed into a plural noun.

But, we have to follow a specific set of rules for this conversion.

Let us look at these rules one by one.

Rule No.1

We add an -s at the end of a regular noun to pluralize them.

Let us take an example: Cat- Cats We add -s to the word cat to obtain the plural cats

Let us take another example: House - Houses We add -s to the word house to pluralize it.

Rule No.2

To form a plural noun from a singular noun which ends in -s, -ss, -sh, -ch, -x, or -z, we add -es at the end of it.

Let us look at an example Bus- buses We add -es to the end of “bus” to obtain the plural buses.

Let us look at another example Box - Boxes Here the word box ends with -x, we add -es to obtain the plural boxes.

Rule No.3

For the nouns than ends with -f or -fe, we replace f with -ve before adding the -s to form the plural version.

Let us look at an example: Wife- wives As wife ends with -fe, we first replace it with -ve and then add -s to form wives.

But there are some exceptions to this the rule.

For example: Chef - Chefs Even though the word ends with -f, we do not replace it with -ve first, instead we directly add -s to the end.

Rule No.4

For a singular noun ending with -y, we check the letter that is present before -y, if it is a consonant, we replace it with -ies to form its plural.

Let us look at an example: Puppy - puppies The letter present before -y in the word puppy is “p”, and “p” is a consonant. Therefore we replace it with -ies

Rule No.5

For a singular noun ending with -y, we check the letter that is present before -y, if it is a vowel, we simply add -s at the end of it to form its plural.

Here is an example: Boy- boys The letter present before -y is “o”, which is a vowel, therefore we simply add -s at the end of it to form its plural.

Rule No.6

For a singular noun that ends with -o, we add -es at the end of it to make it plural

Let us look at an example: Tomato- tomatoes Here as the word tomato ends with -o, we simply add -es at the end of it to obtain its plural

This rule too has exceptions.

Here is an example of an exception to this rule: Piano- pianos As this is an exception, we do not add -es to the end, instead, we add -s to obtain the plural.

Rule No.7

For a singular noun that ends in -us, we replace -us with -i to make it plural.

Here is an example: Cactus- cacti Here, the word cactus ends with -us, so we replace -us with -i.

Rule No.8

Despite the presence of all these rules, some nouns don't change even when pluralized

For example: Sheep- sheep Sheep is one such noun that doesn’t change even when pluralized. We never use sheeps.

So, these are a few rules that we have to keep in our mind while forming a plural noun from a singular noun.

Now, let’s have a quick recap of what we learnt.

There are two forms of nouns: Singular and Plural

To change a singular noun to a plural one, check the letter or letters it ends with and then applies the correct rule.

There are certain singular nouns which do not change even when pluralized.

That's all folks!
