Is paradox an abstract noun

Answer 1

Yes, paradox is an abstract noun.

Nouns refer to people, places, and things. Nouns can be divided into concrete nouns and abstract nouns. Abstract nouns are ones that you cannot detect with your senses; you cannot see, hear, smell, taste, or feel them. An abstract noun is a certain category of thing, such as a concept, idea, feeling, experience, state of being, quality, event, or other intangible thing. Abstract nouns include heroism, equality, jealousy, and intelligence. In contrast, concrete nouns are ones with which you can physically interact, ones you can detect with your senses. Concrete nouns include tadpole, oak, blanket, cinnamon, and drum.
