An abstract term refers to a concept, idea, experience, trait, feeling, or other item that cannot be seen, heard, tasted, smelt, or touched. Words that are abstract, lacks substance and realism. Proverbs frequently employ abstract nouns.
Scholars defined an abstract noun as a noun that refers to a concept or a universal quality rather than a material object. For example, we can use the noun "fear" to describe a feeling or condition. You may be able to see the thing that makes you afraid, like a spider, but you cannot see or touch your fear.
