* Have singular and plural forms: Examples include "book" (singular) and "books" (plural).
* Can be used with numbers: "Two apples", "five cats".

Count nouns are the opposite of mass nouns, which represent things that can't be counted individually (like water, air, or sand). Mass nouns have only a singular form and cannot be used with numbers.
Examples of Mass Nouns:
* Liquids: water, milk, juice
* Substances: sand, air, wood
* Concepts: information, advice, knowledge
Key Points:
* Count nouns are essential for expressing quantity and specificity.
* Identifying whether a noun is countable or not helps to ensure grammatically correct sentences.
* Understanding count nouns is fundamental to the study of English grammar.
