Usage

Nouns are words for things. There are three main types of nouns:

1. Countable nouns are nouns that have a plural form--they can be counted.

    boy/boys, chicken/chickens, man/men

2. Uncountable nouns are nouns that do not have a plural form--they cannot be counted.

    water, air, milk, dirt

3. Collective nouns are names for a group/collection of people/animals/things.

    team, army, family

Grammar Focus

In English, most nouns are not defined as masculine/feminine/neutral. However, some names of animals and types of people do have masculine and feminine forms.

    "Is that horse a stallion, or a mare?"

    "This is the ladies' room; the men's room is over there."

Here are some more nouns of this type:

    actor/actress hero/heroine host/hostess businessman/businesswoman man/woman duke/duchess prince/princess count/countess waiter/waitress god/goddess widower/widow salesman/saleswoman steward/stewardess

    For professions it is now more acceptable to use a gender neutral form whenever possible.
    policewoman/policeman >>> police officer
    salesman/saleswoman >>> salesperson
    chairman/chairwoman >>> chair

There are many ways of making plurals of countable nouns using -s.

1. The most common way is by simply adding -s to the singular form.

    "Does she have one book or two books?"

2. Singular nouns ending in -s, -sh, -ch or -x are made plural by adding -es.
glass/glasses bush/bushes stitch/stitches box/boxes

3. Most singular nouns ending in -f change -f to -v and add -es to make the plural form. There are a few nouns ending in -f that behave normally and add -s in the plural form. Here are common examples of both types:

    calf/calves half/halves leaf/leaves loaf/loaves shelf/shelves chief/chiefs cliff/cliffs roof/roofs

4. Singular nouns ending in -fe change -fe to -ves in the plural form.

    knife/knives life/lives wife/wives

5. Singular nouns ending in a -y after a consonant change -y to -ies to make the plural.

    city/cities company/companies factory/factories

6. Singular nouns ending in -y after a vowel add -s in the plural form.

    boy/boys key/keys toy/toys trolley/trolleys

7. Some singular nouns ending in -o add -es in the plural while others add -s. It is important to learn the most common nouns of both types.

    hero/heroes potato/potatoes tomato/tomatoes volcano/volcanoes dynamo/dynamos banjo/banjos piano/pianos solo/solos

Here are some of the special cases which do not follow these rules:

Some countable nouns do not add -s in the plural.

    medium/media alumnus/alumnae libretto/libretti

Some nouns, especially the names of some animals and fish, have the same form in singular and plural.

    antelope/antelope buffalo/buffalo deer/deer fish/fish trout/trout sheep/sheep salmon/salmon

Some nouns have no singular form.

    barracks headquarters pliers shorts clothes jeans premises eyeglasses contents manners pyjamas spirits cross-roads means scissors trousers outskirts savings valuables

Certain compound nouns add -s to the first word, but not the second in the plural form.


    editor-in-chief >>> editors-in-chief
    father-in-law >>> fathers-in-law
    son-in-law >>> sons-in-law
    passer-by >>> passers-by

Some nouns change vowels and/or add consonants in the middle of the word, or add -en in the plural form:

    foot/feet child/children goose/geese ox/oxen man/men woman/women mouse/mice louse/lice

Certain singular nouns ending in -ex or -ix remove the last two letters and add -ices in the plural form.

    appendix/appendices index/indices vortex/vortices

Certain nouns of French origin used commonly in English use the French plural form.

    bureau/bureaux gateau/gateaux tableau/tableaux

Uncountable nouns have no plural form, and cannot be counted in their basic form.

    milk sugar soap meat

Some uncountable nouns can be counted by naming the container/shape/weight in which they are found.

    a bottle of milk two bags of sugar many bars of soap

Some uncountable nouns can be counted using a piece of, two pieces of, etc.

    a piece of furniture two pieces of luggage three pieces of cheese

Collective nouns can be singular or plural and name groups or collections of people, animals, or things.

    a crowd of people a herd of cows a bunch of bananas

When the collective noun is the subject of the sentence, it is usually treated as singular.

    "A flock of geese has landed on the lake."

    "A team of horses was stolen from the barn."

When the individual members of the collective group are important, the noun is treated as plural.

    "The police are cracking down on traffic offenders."

Otherwise, many nouns for groups of people are treated as singular.

    "The team is really doing well this year."

    "Our staff has increased since 1990."
