**Plural Nouns - Rules, Types, and Examples**
In English, nouns are categorized into singular and plural forms based on their quantity. This classification applies primarily to common nouns, as proper nouns typically refer to specific people or places and do not follow pluralization rules. This article will delve into the details of plural nouns, including their definitions, rules, and examples.
### **Definition of a Plural Noun**
According to the Merriam-Webster dictionary, the term "plural" refers to grammatical forms used to indicate more than one entity. Therefore, a noun that represents more than one person, place, or thing is known as a plural noun.
### **Changing a Singular Noun to a Plural Noun**
Pluralizing common nouns in English can involve adding different suffixes like 's', 'es', 'ies', 'ves', or making changes such as altering 'us' to 'i' or 'is' to 'es'. Some nouns retain the same form in both singular and plural, while others (known as irregular nouns) undergo unique transformations.
### **Examples:**
**Adding ‘s’**
- **Book** – books
- **Apple** – apples
- **Table** – tables
**Adding ‘es’**
- **Bus** – buses

- **Glass** – glasses
**Adding ‘ves’ for nouns ending with ‘f’ or ‘fe’**
- **Leaf** – leaves
- **Half** – halves
- **Shelf** – shelves
**Adding ‘es’ to nouns ending with an ‘o’**

- **Echo** – echoes

### **Nouns with a Common Singular and Plural Form**
Some nouns have identical singular and plural forms. These include:
- **Sheep** – sheep
- **Species** – species

### **Irregular Nouns**

- **Man** – men
- **Woman** – women
- **Child** – children
- **Tooth** – teeth
- **Foot** – feet
- **Mouse** – mice
### **Plural Form for Hyphenated Nouns and Relationships**
In hyphenated nouns, typically, the first word is pluralized:
- **Mother-in-law** – mothers-in-law
- **Father-in-law** – fathers-in-law
- **Daughter-in-law** – daughters-in-law
### **The Golden Rule of Using Plural Nouns in Sentences – Subject-Verb Agreement**
When using plural nouns, the verb must agree in number. For plural subjects, the verb form should also be plural. Common plural verb forms include **are** (simple present tense), **were** (simple past tense), **have** + past participle, and so on.
**Examples:**
- The **students** **are** studying for their exams.
- **Dogs** **have** always been loyal companions.
