THE NOUN
Basic Uses
The noun may be a single word or a phrase (noun phrase). The noun phrase may consist of an article and/or adjectives and/or prepositional phrases. The noun can function as subject of a sentence, object of a verb, object of a preposition, predicate nominative, complement of an object, in apposition, and in direct discourse:
Subject: The office was quiet.
The house with green shutters was for sale.
Direct object of a verb: He locked the office.
Indirect object of a verb: He gave his client the papers.
Object of a preposition: The business was in bankruptcy.
The file is in the office.
Predicate nominative: Ms. Adams is the managing partner.
Complement of an object: They made Ms. Adams managing partner.
In apposition: Ms. Adams, the managing partner, wrote that memo.
In direct discourse: Ms. Adams, may I present Mr. Wilson.
Nouns are often classified as to whether they are proper nouns (Eiffel Tower, White House), common nouns (tower, house), abstract nouns (honor, love), concrete nouns (desk, flower), or collective nouns (team, government). American English typically uses a singular verb with a collective noun (the team is), while British English typical uses a plural verb (the government are).
Most nouns are neuter, showing no distinction as to whether having a masculine or feminine reference. However, a few nouns ending in -ess (as empress, hostess) are feminine in gender, and some others have a specific gender. For example: husband, wife, father, mother, brother, sister. The names of certain animals also have a specific gender, for example, bull/cow, stag/doe. When it is necessary to specify the gender of a neuter noun, the noun is usually modified with words like male, female, man, woman (a male parrot, women painters).
The Noun As Adjective
The noun has the function of an adjective when it precedes another noun:
olive oil
business management
emergency room
dog house
The Formation of the Plural
The plural of nouns is formed by adding the suffix -s to the singular noun:
book → books
cat → cats
When the singular noun ends in -s, -x, -z, -ch, or -sh, the suffix -es is added to the singular:
cross → crosses
fox → foxes
witch → witches
wish → wishes
For a singular noun ending in -z, the last letter is doubled before adding the suffix -es:
buzz → buzzes
quiz → quizzes
For a singular noun ending in -y preceded by a consonant, the -y changes to -i and the suffix -es is added:
fairy → fairies
pony → ponies
guppy → guppies
For a singular noun ending in -y preceded by a vowel, the -y usually does not change when the suffix -s is added:
boy → boys
attorney → attorneys
Some words that end in -uy sometimes change the -y to -i:
guy → guys
soliloquy → soliloquies
There are a few nouns that do not always change in the plural:
fish
