The 6 Rules For Understanding Plural Nouns in English.

Imagine living in a town with only one clothes shop.

You walk in to see only one l pair of jeans hanging on the only rack, and it's not your size.

Next, you are hungry so you walk down the street to the only fast food restaurant in town and there’s only one kind of hamburger on the menu. You have no choice but to order and eat that.

Then you go to school and find that you’re the only student in the class.

How boring life would be if there were only one of everything!

Well, don't worry, plurals are here to save your from the boredom!

In real life, there would be several clothes stores in your town with racks of many clothes to choose from. Hungry? No problem. Walk down any of the streets in town and there’ll be countless fast-food restaurants serving unlimited fast food. 

Next, step into your class and it’s filled with students from all over your town, chatting and laughing.

Now that’s more like it.

We really do need those plurals, don’t we? They make life interesting.

So what are those mysterious plurals, and how do they work in English? Let’s take a brief look before we get down to six specific spelling rules for making nouns plural. I’ll be giving you some common examples of nouns for each rule, as well as important exceptions to remember.

Your job is to find more nouns and add them to the list for each rule. Consider this an English plural reference guide that you can continue to use as your English advances.
 

How Do Plurals Work in English?

A singular noun in English refers to one person, thing, place, or idea. A plural noun refers to more than one person, thing, place, or idea.

Some languages make no grammatical distinction between singular and plural. But in English, we have some unusual rules to make our nouns plural.

The difference between the singular and plural forms of a noun is reflected in spelling. As you’ll see below, there are a number of spelling rules that can be applied to change a noun from singular to plural. The pronunciations of the plural and singular forms are usually slightly different as well.

Like many English rules, there are exceptions that apply only to certain plural nouns. What’s also interesting is that some nouns are always plural, some are always singular and some look the same in their singular and plural forms.

I know this may sound slightly overwhelming right now. But I’m going to simplify it for you and tell you exactly how these rules work. The list below would also be useful as a reference whenever you need to refresh your memory.

How to Form the Plural of Any English Noun: 

6 Simple Rules with Examples and Exceptions.

1. When to Add -s

For the most regular English Nouns, you simply add the letter -s after the noun. Easy, right?

Here are a few common examples:

dog → dogs

car → cars

apple → apples

Nouns Ending in -th or -ph

If the noun ends in -th or -ph, simply add an -s after it, just like with the common words above.

mouth → mouths

photograph → photographs

Nouns Ending in -o

The general rule for nouns ending with the letter -o is to simply add -s after it.

Some common examples of such nouns are:

photo → photos

taco → tacos

piano → pianos

Exception: Add -es Instead

The exception to this rule is that for some nouns ending with the letter -o, you add -es after the noun instead. There aren’t any strict grammar rules here, so pay attention to these words when you encounter them and try to memorize them.

potato → potatoes

tomato → tomatoes

hero → heroes

cargo → cargoes

Nouns Ending in -f or -fe

The general rule is that for nouns ending in the letter -f or -fe, you simply add an -s at the end.

Here are some common examples:

roof → roofs

giraffe → giraffes

Exception: Use -ves Instead

The exception to this rule is that for some nouns ending in -f or -fe, instead of adding -s after the noun, you drop the -f or -fe and add -ves.

Here are a few common examples that are helpful to remember:

leaf → leaves

knife → knives

Nouns Ending in -on

For most nouns ending in -on, you simply add -s at the end.

lemon → lemons

canyon → canyons

salon → salons

Exception: Use -a Instead

For certain nouns ending in -on, drop -on and add -a at the end of the word.

You probably won’t encounter this exception very often, but it’s still important to know—especially if you’re using English for school or science, where you might need to use these words:

criterion → criteria

phenomenon → phenomena

2. When to Add -es

Some nouns always end in -es in the plural form.

Nouns Ending in -s, -x, -z, -sh or -ch

For nouns ending with the letters -s, -x, -z, -sh or -ch, simply add -es after the noun.

These examples show nouns with each of these endings:

bus → buses

box → boxes

buzz → buzzes

wish → wishes

watch → watches

Nouns Ending in -is

You still need -es to form the plural here, but you don’t just stick it onto the singular form.

For nouns ending in -is , drop the -is and then add -es.

Let’s look at some common examples:

axis → axes

oasis → oases

crisis → crises

3. When to Add -ies

There’s only one common type of word where you need to add -ies in the plural form. However, as you’ll see below, there’s also an important exception to this rule.

Nouns Ending in -y

For nouns ending with the letter -y, the general rule is to drop the -y and add -ies after the noun.

fairy → fairies

candy → candies

dummy → dummies

Exception: Just Add -s

Good news! There’s actually an easy way to remember when you need this exception. Just look for a vowel before the letter -y in the singular form.

If a vowel comes before the letter -y, then it’s easy. You simply add -s after the noun.

way → ways

monkey → monkeys

toy → toys

guy → guys

4. When to Add -i

Here’s another easy rule that you only need for one type of word.

Nouns Ending in -us

For nouns ending in -us, drop -us and add -i at the end of the word.

A few common examples are:

fungus → fungi

cactus → cacti

stimulus → stimuli

5. When to Do Nothing

As we mentioned earlier, there are a couple types of words where you don’t need to learn different singular and plural spellings.

Nouns with the Same Plural and Singular Forms

There are some words that are exactly the same in their singular and plural forms.

Some common examples are below. You might notice that a lot of these words have to do with biology or animals.

sheep

deer

fish

species

Nouns with No Singular Forms

Then there are some nouns that have no singular forms. This means they’re always plural. So you don’t need to learn a singular form, because there isn’t one.

In general, most of these are things that work in pairs. But we should be careful not to assume that this guideline applies to everything that works in pairs.

You’ll see these most often in clothing vocabulary, such as:

scissors

shorts

pants (or: trousers)

jeans

Nouns with No Plural Forms

These nouns are also called mass nouns. They have no distinct plural forms. Typically, they refer to nouns that often come in groups or nouns that are somewhat abstract. For example:

livestock

news

slang

bravery

love

money

6. When to Remember Irregular Forms

If you’ve been an English learner for some time, you know there’ll always be special cases that don’t fit into any fixed formats or follow any rules. Here we have irregular nouns, which break all of the plural spelling rules we’ve discussed so far.

Yes, irregular nouns are like those children at the playground who walk up the slides instead of sliding down or who stand on the swings instead of sitting on them.

Okay, let’s look at some examples:

child → children (not “childs”)

mouse → mice (not “mouses”)

man → men (not “mans”)

woman → women (not “womans”)

die → dice (not “dies”)

With irregular nouns, there are basically no rules. As you can see, you cannot simply apply any of the rules and exceptions like we’ve done with the other regular nouns. So the only thing you can do is to close your eyes and memorize them and their plural forms.

So now, I hope you have a clearer picture of how to make nouns plural and spell them correctly. It may take some time to become familiar with the rules but that’s okay. To learn them quicker, print out a copy of these rules, and keep them handy for your reference. Pretty soon, you’ll be an expert at plural spellings. 

Good luck and good teaching
