What Is a Noun?

A noun is “a person, place, thing, or idea.” Most nouns come after an article, like "a," "an," or "the." They commonly act as the subject of a sentence. For example, "An uncle should always love his nieces and nephews."

Nouns can also serve as the object of a sentence. That means they'll come after the verb. For example, "He flew away on the unicorn." Nouns also function as names, including people, cities, and more.

Types of Nouns

Did you know there are over 10 different types of nouns? If a noun is referring to a person or place, it’s likely acting as a proper noun (e.g. Melanie, Savannah, Alaska, Spain, and Highclere Castle). An example of that would be, "Uruguay is a beautiful haven for artists and writers."

The opposite of a proper noun is a common noun. These nouns refer to general, unspecified things. In the example above, Uruguay is a proper noun. But, if that line simply read, "The country is a beautiful haven," you'd know the subject was a common noun. Common nouns are neither capitalized nor specific.

Then, there are compound nouns (e.g., uproar and underworld), countable nouns, possessive nouns, and pronouns. It’s common to see both nouns and pronouns in a single sentence: "Ursula stopped the car and jumped out to hug her.”
