Uncountable nouns, also known as mass nouns or non-count nouns, are nouns that cannot be counted or quantified as individual units. They represent substances, concepts, or abstract ideas that are seen as continuous or indivisible. Since they lack a specific quantity, they cannot be used in the plural form or be preceded by "a" or "an." Instead, to refer to an indefinite or specific amount of uncountable nouns, we use quantifiers such as "some," "a lot of," "a little," "much," or expressions like "a glass of water," "a piece of furniture," or "a bit of knowledge."

Examples of uncountable nouns:

• Sand: You cannot say "a sand" or "two sands" because sand is a substance that cannot be counted in separate units.

• Love: Love is an abstract concept that cannot be measured or counted. You wouldn't say "a love" or "five loves."

• Music: Music represents a form of expression that cannot be divided into countable units. You cannot say "a music" or "three musics." Instead, you can say "some music," "a lot of music," or "a beautiful piece of music."
