A common noun is a general, non-specific name for a person, place, thing, or idea. It is not capitalized unless it begins a sentence and does not refer to a particular or specific item.
When identifying common nouns, look for words that do not refer to a specific or unique item. Pay attention to whether the noun is capitalized or not, as common nouns are not capitalized unless they begin a sentence.
Identify the common nouns in the following sentences:
1. The teacher, student, book
