Here are all of the basic rules of noun usage.
Nouns are words that label people, places, things and animals.
Some examples are:
- Boy – Person
- City – Place
- Mattress – Thing
- Dog – Animal
The examples above, however, are only one type of noun (common).
Proper Nouns
There are also proper nouns, which are specific or special names for common nouns.
For example:
- Greg – Name of a person
- Toronto – Name of a place
- Sealy – Name of a mattress
- Lassie – Name of a dog
Additionally, proper nouns have to begin with a capital letter because they are specific names.
Now, notice how all of the examples I gave only talk about one person, place, thing or animal?
Plural Nouns
It’s because these are singular nouns. If you want to turn nouns into more than one (or plural), you have to add an -s to them (most of the time).
For example:
- 1 boy – 3 boys
- 1 place – 3 places
- 1 table – 3 tables
- 1 dog – 3 dogs
However, there are special circumstances when this rule doesn’t apply.
-Y to -I
For instance, if a word ends in a -y, you have to change the -y to an -i and then add -es.
For example:
- 1 city – 3 cities
But if the word had a vowel (a, e, i, o, u) before the -y, this rule doesn’t apply.
For example:
- 1 toy – 3 toys
-F to -V
Another rule is if a word ends in an -f, you have to change it to a -v and then add -es.
For example:
- 1 leaf – 3 leaves
However, some words are exempt from this rule.
If the word ends in -ff, it is exempt.
- 1 cliff – 3 cliffs
There are also some other words that are just exempt.
- 1 belief – 3 beliefs
- 1 chef – 3 chefs
- 1 chief – 3 chiefs
- 1 reef – 3 reefs
(To learn all or most of them, search them online.)
Adding -ES
Also, if a word ends in -s, -x, -o, -ss, -ch, or -sh, you have to add an -es.
For example:
- 1 bench – 3 benches
- 1 bush – 3 bushes
- 1 box – 3 boxes
- 1 loss – 3 losses
- 1 potato – 3 potatoes
Irregular Nouns
In addition to all of that, there are also irregular nouns. These are nouns that don’t follow any plural rule.
For example:
- 1 man – 3 men
- 1 tooth – 3 teeth
- 1 mouse – 3 mice
Countable and Uncountable Nouns
Another important rule to keep in mind is countable and uncountable nouns.
Countable nouns are things you can count, such as apples or teeth.
Uncountable nouns are things you cannot count, such as water, nature or poverty.
This rule is important because it will ensure your subjects and verbs agree and help you pick the right quantifiers.
For example:
- The information is correct.
- The water is cold.
- There is so much snow.
Subjects and Objects
One more thing you have to keep in mind when dealing with nouns is subjects and objects.
Subject nouns are words that are used before verbs or prepositions.
For example:
- The man ran to work.
Object nouns are words that are used after verbs or prepositions.
For example:
- The cyclist bumped the car.
- The mouse scurried under the table.
Collective Nouns
Another thing (sorry) is collective nouns.
Collective nouns are single words used to describe a group of people, things or animals.
It’s important to know these nouns because they represent many people, things, or animals, but act as a singular noun.
Some examples are: family, band, team, herd, pack, pile, stack, collection.
Conclusion
These are the basic rules for nouns.
