Explain the concept of countable and uncountable nouns.

Countable nouns are nouns that can be counted and have a plural form. They refer to objects or things that can be separated into individual units. Examples of countable nouns include books, chairs, and apples.

Uncountable nouns, on the other hand, are nouns that cannot be counted and do not have a plural form. They refer to substances, concepts, or qualities that are considered as a whole or cannot be divided into separate units. Examples of uncountable nouns include water, happiness, and information.

The distinction between countable and uncountable nouns is important because it affects the way we use determiners, quantifiers, and verbs with these nouns. Countable nouns can be used with both singular and plural forms, while uncountable nouns are used only in the singular form. Additionally, countable nouns can be preceded by quantifiers such as "a," "an," "some," or "many," while uncountable nouns are usually preceded by quantifiers like "some," "much," or "a lot of."
