Do you ever hear about this material before? If you are not, please pay attention my explanation about this material and read this material carefully. Oke, check this out.

English plural nouns

In order to change a singular noun to its plural form in English, you usually add “s”. For example, the plural of book is books. The plural of table is tables. These are regular plurals.

But there are many nouns which don’t follow this rule. For example the plural of fish is fish. The plural of tooth is teeth. These are irregular plurals

Regular plurals:

Form:

Add “s” to the noun:

Noun + S

While many plural nouns follow this rule, the spelling sometimes differ.

Examples:

Singular Plural
snake snakes
window windows
box boxes
boy boys
lorry lorries
potato potatoes
knife knives

 Spelling of plurals:

The plural form of most nouns is created simply by adding the letter “s”.

  • more than one snake = snakes
  • more than one girl = girls
  • more than one window = windows

Nouns that end in -ch, x, s, z or s-like sounds, however, will require an es for the plural:

  • more than one witch = witches
  • more than one box = boxes
  • more than one gas = gases
  • more than one bus = buses
  • more than one kiss = kisses

Nouns that end in a vowel + y take the letter s:

  • more than one boy = boys
  • more than one way = ways

Nouns that end in a consonant + y drop the y and take ies:

  • more than one baby = babies
  • more than one lorry = lorries

A lot of nouns that end in o take es in the plural:

  • more than one potato = potatoes
  • more than one hero = heroes
o becomes oes
echo echoes
embargo embargoes
hero heroes
potato potatoes
tomato tomatoes
torpedo torpedoes
veto vetoes

Some nouns ending in o break the above rule and get os in the plural form:

o becomes os
auto autos
kangaroo kangaroos
kilo kilos
memo memos
photo photos
piano pianos
pimento pimentos
pro pros
solo solos
soprano sopranos
studio studios
tattoo tattoos
video videos
zoo zoos

Other nouns ending in o get either os or oes i the plural forms:

o becomes os or oes
buffalo buffalos/buffaloes
cargo cargos/cargoes
halo halos/haloes
mosquito mosquitos/mosquitoes
motto mottos/mottoes
no nos/noes
tornado tornados/tornadoes
volcano volcanos/volcanoes
zero zeros/zeroes

Plurals of nouns that end in f or fe usually change the f sound to a v sound and add s or -es.

  • more than one knife = knives
  • more than one leaf = leaves
  • more than one hoof = hooves
  • more than one life = lives
  • more than one self = selves
  • more than one elf = elves

Plurals formed in this way are sometimes called irregular plurals or mutated (or mutating) plurals.

  • more than one man = men
  • more than one person = people
  • more than one goose = geese

 Nouns that are always singular:

 A handful of nouns appear to be plural in form but take a singular verb:

  • Economics/mathematics/statistics is said to be difficult.

Some nouns never take the s of the plural and are always singular:

  • your luggage / baggage is so heavy
  • I’d like to buy new furniture for the house
  • you can find more information in our website.
