A noun is a word used to name a person, place or thing, an animal or abstract idea. The highlighted words in the following sentences are all nouns:
A noun can function in a sentence as a subject, a direct object, an indirect object, a subject complement, an object complement, an appositive, an adjective or an adverb.
Many common nouns, like engineer or teacher, refer to both men and women. In the past, many English nouns would change form depending on their gender—for example, a man was called an author, a woman an authoress. This use of gender-specific nouns is very rare today. As far as possible, job titles should not imply that the job can be filled only by members of one sex.
Use feminine nouns when women are referred to, or gender-inclusive nouns when a man or woman is not specifically referred to:
Most nouns change their form to indicate number by adding s or es, as illustrated in the following pairs of sentences:
Other nouns form the plural by changing the last letter before adding s. Some nouns ending in f form the plural by deleting the f and adding ves. Some nouns ending in y form the plural by deleting the y and adding ies, as in the examples below:
Some nouns ending in f.
Some nouns ending in y.
Other nouns form the plural irregularly.
If English is your first language, you probably know most of them already: when in doubt, consult a good dictionary.
In the possessive case, a noun or pronoun changes its form to show that it owns or is closely related to something else. Usually, nouns become possessive by adding an apostrophe and the letter s.
You can form the possessive case of a singular noun that does not end in s by adding an apostrophe and s, as in the following examples:
You can form the possessive case of a singular noun that ends in s by adding an apostrophe alone or by adding an apostrophe and s, as in the following examples:
You can form the possessive case of a plural noun that does not end in s by adding an apostrophe and s, as in the following examples:
You can form the possessive case of a plural noun that ends in s by adding an apostrophe, as in the following examples:
Note that a noun in the possessive case frequently functions as an adjective modifying another noun. In the following example,
the possessive noun miner’s modifies the noun face and together with the article the, they make up the noun phrase that is the sentence’s subject.
In the sentence below,
each possessive noun modifies a gerund. The possessive noun dogs’ modifies barking, ducks’ modifies quacking, and babies’ modifies squalling.
In the example below,
the possessive noun platypus’s modifies the noun eggs and the noun phrase the platypus’s eggs is the direct object of the verb crushed.
In the following sentence,
the possessive noun squirrels’ modifies the noun nest and the noun phrase the squirrels’ nest is the object of the infinitive phrase to find.
There are many different types of nouns. Some nouns, such as Canada or Bridget, are capitalized and others, such as badger or tree, are not (unless they start a sentence or appear in a title). In fact, grammarians have developed a whole series of noun types: proper, common, concrete, abstract, countable (also called the count noun), non-countable (also called the mass noun) and collective. You should note that nouns may belong to more than one type. For example, a noun may be proper or common, abstract or concrete, and countable or non-countable or collective.
Always capitalize a proper noun as it represents the name of a specific person, place or thing. The names of days of the week, months, historical documents, institutions, organizations, religions and their holy texts and adherents are all proper nouns. Note that a proper noun is the opposite of a common noun.
In each of the following sentences, the proper nouns are highlighted:
A common noun refers to a person, place or thing in a general sense and is the opposite of a proper noun. It should be written with a capital letter only when it begins a sentence.
In each of the following sentences, the common nouns are highlighted:
You may sometimes make proper nouns out of common nouns, as in the following examples:
A concrete noun names anything (or anyone) that can be perceived through the physical senses (touch, sight, taste, hearing and smell). A concrete noun is the opposite of an abstract noun.
The highlighted words in the following sentences are all concrete nouns:
An abstract noun names anything that cannot be perceived through the five physical senses (touch, sight, taste, hearing and smell), and is the opposite of a concrete noun.
The highlighted words in the following sentences are all abstract nouns:
A countable (or count) noun has both a singular and plural form, and names anything (or any being) that can be counted. A countable noun can be made plural and take a plural verb in a sentence. It is the opposite of a non-countable noun and a collective noun.
In each of the following sentences, the highlighted words are countable nouns:
A non-countable (or mass) noun does not have a plural form and refers to something that is usually not counted. A non-countable noun always takes a singular verb in a sentence. It is similar to a collective noun, and is the opposite of a countable noun.
The highlighted words in the following examples are non-countable nouns:
The word oxygen cannot normally be made plural. Since oxygen is a non-countable noun, it takes the singular verb is rather than the plural verb are.
As a non-countable noun, furniture has no plural and takes the singular verb is heaped.
The noun gravel has no plural. Since gravel is a non-countable noun, it takes the singular verb form is.
A collective noun names a group of things, animals or persons. You could count the individual members of the group, but you usually think of the group as a whole. It is important to recognize collective nouns in order to maintain subject-verb agreement. A collective noun is similar to a non-countable noun, and is roughly the opposite of a countable noun.
In each of the following examples, the highlighted word is a collective noun:
The collective noun flock takes the singular verb spends.
The collective noun jury is the subject of the singular compound verb is dining.
Here the collective noun committee takes the singular verb meets.
Class is a collective noun and takes the singular compound verb was startled.
