An abstract noun is known to be a class of noun that refers to something intangible. These nouns actually refer to certain concepts such as an emotion, a feeling, a quality, or an idea which are not concrete and can't be touched.
These nouns are seen as a word that names something that one cannot see, touch, taste, hear, or smell. This means that they actually nouns that cannot be perceived with the five senses.
