Singular and Plural Nouns

Singular and Plural Nouns (15 Rules, 50 Examples & Worksheet)

What is singular noun?

The singular nouns are words that only refer to one person or thing. They can be used as a subject, direct object, indirect object, predicate nominative, or appositive.

For example: “I went to the store.” This sentence is about the speaker and their experience at the store. It’s also possible for a singular noun to be an appositive such as in this sentence: “Tina was wearing her best dress.”

Here, Tina is being described by what she was wearing which is called an appositive.

What is plural noun?

Plural nouns are words that refer to more than one person, place or thing. They are often used in sentences where we want to talk about a group of people, animals, or things.

Let’s take the sentence “I am teaching a class this semester.” We can change it around and say “The students have been working hard all semester long.” In the first sentence, “class” is singular and in the second sentence, “students” is plural. That means you need to use a proper noun (singular or plural) according to the situation.

It may not seem like much of a difference at first but it will make your writing sound awkward if you don’t get it right! The best way is to learn the rules of plural nouns.

Types of Plurals

A lot of people don’t know about the types of plural nouns, but it’s important to understand that there are three types of plurals:-

  1. Regular Plurals
  2. Irregular Plurals
  3. Compound Words

The plural noun rule is one of those things that can trip you up when you’re writing sentences

Regular Plurals

Regular plurals end in s or es. For example, bag -> bags, toy -> toys, pen -> pens etc.

Irregular Plurals

Irregular plurals have a different spelling for their endings than they do for singulars. For example ox -> oxen, goose -> geese etc.

Compound Plurals

Compound words are made up of two words put together to make one word. For example, “bookcase” is a compound word with two parts – book and case. To form the plural form of this word, we would simply add an ‘s’ at the end (bookcases).

It’s easy to remember these rules if you think about them like this – just add an ‘es’ for regular plurals and an ‘s’ for irregular ones!
