Abstract nouns can be common or proper nouns. Whether a noun is abstract or concrete is determined by its definition or its use, not whether it is common or proper.
- A common noun is a Word for any person, place, or thing.
- A proper noun is the name of a person, place, thing, or a title.
- A concrete noun is a Word for something that can be experienced by any of the five physical senses; something that can be seen, heard, smelled, tasted, or touched.
- An abstract noun is a Word for something that can not be experienced by any of the five physical senses; it is something that is known, thought, believed, understood, or learned, felt emotionally.
Examples:
- Common, concrete noun: sandwich
- Common, abstract noun: peace
- Proper, concrete noun: Big Mac
- Proper, abstract noun: 'War and Peace' by Leo Tolstoy
