What defines count nouns?

Count nouns are defined by their ability to be counted and to take plural forms. This means that items categorized as count nouns can be quantified using numbers, such as one apple, two apples, three apples, and so on. They typically represent distinct, individual entities that can exist in determined quantities, allowing for both singular and plural variations. For instance, you can have one cat, two cats, three cats, etc., demonstrating their countability and the concept of plurality associated with them. This characteristic distinguishes count nouns from mass nouns, which refer to substances or concepts that cannot be easily counted, such as rice or information.
