What Is a Noun?

A noun is a person, place, thing, or idea. When we use them in our writing, we often need to place an article before them, such as “a,” “an,” or “the.” For example, “a tractor,” “an arboretum,” or “the trellis.”

One of the primary functions of nouns is to act as the subject of the sentence. So, in the sentence, “Her xylophone is black,” “xylophone” is a noun. Nouns are often direct objects, too. In the sentence, “She plays the xylophone,” “xylophone” acts as the direct object. It’s the object of the verb, “plays.”

Types of Nouns

Nouns are organized into several different categories. Here are five of the most varieties:

  • Proper nouns name specific things, like the names of people, cities, states, countries, buildings, and books. As proper nouns, they are capitalized. So, “Xander” is a proper noun, but “man” is a common noun.
  • Common nouns refer to general items, such as “city,” instead of “Xi’an,” (a city in China).
  • Abstract nouns are used when you can’t touch the noun. These nouns are theoretical, such as “love” or “time.”
  • Collective nouns refer to large groups, such as a “troop” of baboons or a “herd” of sheep.
  • Possessive nouns demonstrate ownership over something else. For example, with “Xavier’s X-ray,” “Xavier’s” is a possessive noun, indicating that it’s his X-ray.
