Is grains or seeds a common proper noun?

"Grains" and "seeds" are not common proper nouns. They are common nouns, meaning they refer to general categories of things.

Here's why:

* Common nouns are words that refer to general things, not specific ones. They are not capitalized unless they start a sentence.

* Proper nouns are specific names of people, places, or things. They are always capitalized.

Examples:

* Common Noun: grain (referring to any type of grain)

* Proper Noun: Wheat (referring to a specific type of grain)

* Common Noun: seed (referring to any type of seed)

* Proper Noun: Sunflower seed (referring to a specific type of seed)
