* Proper nouns refer to specific, unique people, places, or things. They are always capitalized.
* Examples: John, London, the Eiffel Tower.
* Common nouns refer to general categories of people, places, or things. They are not capitalized unless they start a sentence.
* Examples: man, city, building.
"Cherry" is a common noun because it refers to a general type of fruit. It is not the name of a specific cherry.
However, if you were referring to a specific type of cherry, like "Bing cherry" or "Maraschino cherry," those would be considered proper nouns and would be capitalized.
