Definition & Meaning of "abstract noun"

What is an "abstract noun"?

An abstract noun is a type of noun that refers to ideas, qualities, emotions, or concepts that cannot be perceived through the five senses. Unlike concrete nouns, abstract nouns represent things that are intangible and exist only in thought or as a state of being. Examples of abstract nouns include "love," "freedom," "happiness," "justice," and "courage." These nouns express concepts that cannot be seen, touched, or physically measured but are understood through experiences and feelings. Understanding abstract nouns is important for discussing emotions, values, and complex ideas.
