Nouns that name things you cannot perceive by the senses are nouns?

You're close! The nouns that name things you cannot perceive by the senses are called abstract nouns.

Here's a breakdown:

* Concrete nouns: These are nouns that refer to things you can perceive with your senses (sight, touch, taste, smell, hearing). For example, "table," "flower," "music," "sunshine."

* Abstract nouns: These are nouns that refer to ideas, concepts, emotions, qualities, or states of being. They are things you can't touch, see, smell, taste, or hear. For example, "love," "justice," "peace," "anger," "freedom," "time."
