Countable nouns in English

Countable nouns.

In English, there are two kinds of noun: countable nouns and uncountable nouns.
COUNTABLE NOUNS IN ENGLISH: are things that we can count and have both a singular and plural form.

one dog, two dogs

an apple, two apples

one boy and one girl, two boys and three girls

a film, several films

a man, a few men

one person, two people

this door, these doors

that house, those houses

The plural of countable nouns is generally indicated by adding ‘S’ to the end of word.

chair = chairs

flower = flowers

week = weeks

window = windows

Nouns that finish with a vowel + ‘Y’ (AY, EY, OY) take the ‘S’ to indicate the plural.

boy = boys

day = days

key = keys

play = plays

However, nouns that finish with a consonant + ‘Y’ (BY, KY, RY, DY, LY) take ‘IES’ to indicate the plural.
in this case the ‘Y’ is removed and replaced with an ‘I’

baby = babies

fairy = fairies

fly = flies

lady = ladies

sky = skies

For nouns that finish with a sibilant ‘S’, ‘SS’, ‘SH’, ‘CH’, ‘X’, ‘Z’ the plural is indicated with ‘ES’.

bus = buses

dish = dishes

church = churches

box = boxes

quiz = quizzes (N.B. double ‘Z’)

Most nouns that finish with ‘F’ / ‘FE’ take ‘S’.

However, some nouns that finish with ‘F’ / ‘FE’ take ‘VES’.

wife = wives

life = lives

knife = knives

thief = thieves

self = selves

Wolf = wolves

We add ‘S’ to nouns that finish with ‘O’ if they are foreign words, musical words or words ending in 2 vowels.

avocado = avocados

zoo = zoos


echo = echoes

embargo = embargoes

tomato = tomatoes

potato = potatoes

hero = heroes

Please note:

The final S is pronounced /s/ when it is preceded by an unvoiced consonant sound ( k, p, t, ck, ph, and unvoiced th /θ/ );

Books /s/ Cats /s/ Clocks /s/ Months /s/

it is pronounced /z/ when it is preceded by a voiced consonant sound (b, d, g, l, m, n, r, v and voiced th /ð/ and the vowel o)

Flags /z/ Roads /z/ Balls /z/ Goes /z/

It is pronounced /iz/ when the nuon finishes with s, ss, sh, ch, x, z, ce, se, ge

Some plurals are irregular.

woman = women

child = children

ox = oxen

person = people

tooth = teeth

goose = geese

foot = feet

louse = lice

mouse = mice

die = dice

penny = pence, Pennies (coins)

Many compound nouns that end with an irregular plural follow the same pattern.

business woman = business women

Some plurals are the same as the singluar and use both the plural and singular verb

sheep (is)

sheep (are)

deer (is)

deer (are)

Some nouns are always used in the plural form (they), do not have a singular form, and are used with the verb form used for the third person plural (are/have/were etc.).
