Countable and Uncountable Nouns - English Grammar
Countable and uncountable nouns are two categories of nouns in English grammar. Understanding the difference between these two types of nouns is essential for proper usage in sentences.

Countable Nouns
- Countable nouns refer to individual items that can be counted and have a plural form.
- Examples of countable nouns include "dog," "apple," and "book."

Uncountable Nouns
- Uncountable nouns, also known as mass nouns, refer to substances, concepts, or qualities that cannot be counted as individual units.

- Uncountable nouns do not have a plural form and are used with specific quantifiers like "some," "a little," and "much."

Distinguishing Between Countable and Uncountable Nouns
- One way to determine whether a noun is countable or uncountable is to consider if it can be expressed as a plural form.
- Countable nouns can be made plural by adding "-s" or "-es" at the end, while uncountable nouns do not change form in the plural.
- Additionally, countable nouns can be preceded by numbers or quantifiers, whereas uncountable nouns are typically used with mass quantifiers.

Examples:
- Countable noun: "There are three dogs in the yard."
