Concept:An abstract noun names an idea, quality, or state that cannot be touched, seen, or felt. It refers to something experienced mentally or emotionally.
Explanation:The word ‘adversity’ means a difficult or challenging situation. It is not a physical object like a table or a person. You cannot touch or see adversity; you can only experience it. Therefore, it is an abstract noun.
Common nouns name general classes of persons, places, or things (e.g., city, teacher). Proper nouns name specific individuals or places (e.g., Delhi, Ravi). Collective nouns name groups (e.g., team, flock). Adversity does not fit any of these categories; it describes a state or condition.
