In English grammar, a significant number of nouns can function as both countable and uncountable, with their meaning often shifting depending on the context. This duality allows for nuanced expression, distinguishing between a general substance or concept and specific, individual units.
Countable nouns are those that can be counted and have both singular and plural forms (e.g., one book, two books). Uncountable nouns, also known as mass nouns, refer to substances, concepts, or abstract ideas that are not typically counted and do not usually have a plural form (e.g., water, information).
Here is a list of common nouns that can be both countable and uncountable, along with explanations and example sentences to illustrate the difference.
