Countable noun: A countable noun is a noun that can be counted, such as "dog," "book," or "chair."

Uncountable noun: An uncountable noun is a noun that cannot be counted, such as "water," "air," or "music."

Concrete noun: A concrete noun is a noun that refers to a physical object that can be perceived through the senses, such as a "chair," "tree," or "desk."
