However, it's possible you're referring to specific types of nouns, which could include:
* Proper Nouns: These are names of specific people, places, or things. They are always capitalized.
* Examples: John, London, Amazon River, Titanic
* Collective Nouns: These refer to a group of individuals, but are treated as a single unit.
* Examples: team, flock, family, jury
* Abstract Nouns: These refer to concepts, ideas, qualities, or feelings that cannot be touched.
* Examples: love, justice, freedom, happiness
* Compound Nouns: These are formed by combining two or more words.
* Examples: birthday, high school, toothbrush
* Concrete Nouns: These refer to physical objects that can be touched and experienced with the senses.
* Examples: tree, chair, book, water
If you can provide more context or an example of what you mean by "special nouns," I might be able to give a more precise answer.
