What is a Noun?

noun (noun): a word (except a pronoun) that identifies a person, place or thing, or names one of them (proper noun)

The simple definition is: a person, place or thing. Here are some examples:

• person: man, woman, teacher, John, Mary
• place: home, office, town, countryside, America
• thing: table, car, banana, money, music, love, dog, monkey

Note that any of the above can also be referred to by a pronoun. And note that names like John or America are called "proper nouns".

The problem with the simple definition above is that it does not explain why "love" is a noun but can also be a verb.

Another (more complicated) way of recognizing a noun is by its:

1. ending
2. position
3. function

1. Noun ending

There are certain word endings that show that a word is a noun, for example:

• -ity → nationality
• -ment → appointment
• -ness → happiness
• -ation → relation
• -hood → childhood

But this is not true for the word endings of all nouns. For example, the noun "spoonful" ends in -ful, but the adjective "careful" also ends in -ful.

2. Position in sentence

We can often recognise a noun by its position in the sentence.

Nouns often come after a determiner (a determiner is a word like a, an, the, this, my, such):

• a relief
• an afternoon
• the doctor
• this word
• my house
• such stupidity

Nouns often come after one or more adjectives:

• a great relief
• a peaceful afternoon
• the tall, Indian doctor
• this difficult word
• my brown and white house
• such crass stupidity

3. Function in a sentence

Nouns have certain functions (jobs) in a sentence, for example:

• subject of verb: Doctors work hard.
• object of verb: He likes coffee.
• subject and object of verb: Teachers teach students.

But the subject or object of a sentence is not always a noun. It could be a pronoun or a phrase. In the sentence "My doctor works hard", the noun is "doctor" but the subject is "My doctor".
