A noun refers to a person, place, or thing (objects, ideas, or events).
There are three basic types of nouns: Proper, Common, and Collective Nouns.
Proper nouns are capitalized and name specific persons, places or things.
Common nouns identify general categories and are not capitalized, not even when used in conjunction with proper nouns.
Collective nouns refer to a group of people, animals, objects or other units.
Examples of Proper Nouns: Bakers College, General Mills, Jane Thurgood, etc.
Examples of Common Nouns: university, company, woman, cat, ship, etc.
Examples of Collective Nouns: trustees, management, board of directors, litter, fleet, etc.
