Penjelasan:

1.Common Nouns name people, places, or things that are not specific. They are not capitalized unless they are in a place in the sentence that requires a capital letter (such as the first word in a sentence).

2.Proper Nouns name specific people, places, or things. They begin with a capital letter.

3.Compound Nouns are made up of two or more words. These words may have no space between them (closed compounds), a space between them (open compounds), or a hyphen between them (hyphenated compounds).

4.Collective Nouns refer to things or people as a unit. You may treat these as singular nouns or plural nouns depending on what aspect of the noun you want to highlight

5.Possessive Nouns show ownership, and we use apostrophes to create them. (They are strange because they actually function as adjectives!)
