Count and Non count Nouns
Count nouns are nouns that can be counted (e.g., a book, two friends, three cars, etc.). A count noun may be preceded by a or an in the singular; it takes a final -s or -es in the plural.
Noncount (or mass) nouns refer to things that cannot be counted (e.g., money, rain, snow, butter, wind, air, clothing, etc.). Noncount nouns are not preceded by a or an and have no plural form.
