Explanation:
Nouns are words used to identify (give a name to) things, places, people, ideas, feelings etc.
A common noun refers to something more general (e.g. state) while a proper noun specifies something in particular (e.g. California).
A concrete noun refers to tangible things, those that can be perceived by one or more of our five sense (e.g. apples). An abstract noun refers to ideas, qualities, feelings, actions etc. (e.g. intelligence)
