Breaking Down Number Inflected Nouns

Do you ever get confused about whether to write mouse or mice? Don’t worry, you’re not alone! It’s important to understand how nouns change depending on if there’s one or more of them.

Get ready to dive into noun number inflection and make it as easy as pie.

In studying the inflection of nouns and pronouns, we have to consider gender, number, person, and case.

Gender

Gender is how we categorize people based on their sex. We show gender, whether it’s masculine, feminine, or neutral, by the noun’s meaning or by the pronouns we use with it (like ‘he’, ‘she’, or ‘they’).

Numbers

Numbers help us know if a word is about one or many things (like one dog, two dogs)

Person

Person tells us if the nouns refer to
1. the speaker,
2. the person being talked to, or
3. the person or thing being talked about.

You can usually figure out who it’s talking about from the context, pronouns, and verb choice.

Case

Nouns change case to show their relationship to verbs, prepositions, or another noun. (like ‘the dog’s bone’ showing possession).

We’re talking about number inflected nouns in this blog.

What is Number Inflection?

Number inflection in grammar is just a fancy way of saying how a noun changes to show if it’s talking about one thing or more than one which are the only two options.

The singular number denotes but one person, place, or thing. The plural number denotes more than one person, place, or thing.

Plurals of Singular Nouns

The following rules are used to form plurals of singular nouns.

1. Most nouns add ‘s’ or ‘es’ to the singular.

♦ boy, boys
♦ stove, stoves
♦ bench, benches

2. Nouns ending in ‘x’, ‘s’, ‘ss’, ‘ch’, ‘sh’, or ‘x’, add ‘es’ to the singular.

♦ fox, foxes
♦ wish, wishes
♦ glass, glasses
♦ coach, coaches
♦ buzz, buzzes

3. Nouns ending in y preceded by a vowel (a, e, i, o, u) add ‘s’.

♦ valley, valleys
♦ soliloquy, soliloquies
♦ colloquy, colloquies

Most proper names ending in ‘y’, take the plural of ‘s’
♦ Rowley, Rowleys
♦ Mary, Marys
♦ Murphy, Murphys

4. When ‘y’ is preceded by a consonant (any letter other than a vowel), ‘y’ is changed to ‘i’ and ‘es’ is added.

♦ army, armies
♦ pony, ponies
♦ sky, skies

5. Most nouns ending in ‘f’ or ‘fe’ add ‘s’.

♦ Scarf, scarfs
♦ safe, safes.

A few change ‘f’ or ‘fe’ to ‘v’ and add ‘es’.

♦ wife, wives
♦ self, selves
♦ wolf, wolves

Some others are beef, calf, elf, half, leaf, loaf, sheaf, shelf, staff, thief, life.

6. Most nouns ending in ‘o’ add ‘s’.

♦ cameo, cameos
♦ folio, folios
♦ piano, pianos

Several nouns ending in ‘o’ are preceded by a consonant add ‘es’.

♦ volcano, volcanoes
♦ hero, heroes
♦ potato, potatoes

The most important of the latter class are: buffalo, cargo, calico, echo, embargo, flamingo, hero, motto, mulatto, potato, tomato, tornado, torpedo, veto.

7. Letters, figures, characters, etc., add the apostrophe and s (‘s).

♦ 6’s, c’s, t’s, #’s.

Irregular Noun Inflection

The English language likes to throw curveballs. Some nouns change in a way that doesn’t follow the usual pattern.

♦ child becomes children
♦ mouse becomes mice

These are called irregular inflections, and they can be a bit of a brainteaser.

For instance, why do we say ‘feet’ instead of ‘foots’ when talking about more than one foot.

Or consider ‘person’ and ‘people’.

And don’t forget ‘tooth’ and ‘teeth’, ‘man’ and ‘men’, ‘woman’ and ‘women’.

The list goes on with ‘goose’ turning into ‘geese’, ‘ox’ into ‘oxen’, and ‘louse’ into ‘lice’.

These irregular forms don’t have a one-size-fits-all rule, which can be confusing

RelateSocial: connect with customers!

Special Cases in Number Inflection

Then there are the special cases. Some nouns stay the same in both singular and plural forms,

♦ sheep
♦ species
♦ Japanese

Plurals with Two Meanings

A few nouns have two plurals, but usually with some difference in meaning.

♦ brother
brothers (relatives)
brethren (members of the same society)

♦ horse
horses (animals)
horse (cavalry)

♦ foot
feet (parts of the body)
foot (infantry)

♦ sail
sails (on vessels)
sail (vessels in a fleet)

♦ head
heads (in usual sense)
head (of cattle)

♦ fish
fishes (individually)
fish (collectively)

♦ cloth
cloths (pieces of cloth)
clothes (garments)

♦ die
dies (for stamping)
dice (for gaming)

Compound Nouns

The last part of compound nouns usually gets an ‘s’ when you make them plural.

♦ spoonful, spoonfuls
♦ boathouse, boathouses

Non English Plurals

Others, especially those borrowed from other languages, follow different rules and keep their non-english plurals, Some of the common ones include. (think ‘cactus’ to ‘cacti’).

This shift reflects a broader move towards more inclusive and nondiscriminatory language in our society.

Nouns that are Only Plurals

Certain nouns are only plural.

♦ athletics
♦ billiards
♦ dregs
♦ nuptials
♦ oats
♦ scissors
♦ shears
♦ suds
♦ tweezers
♦ tongs
♦ trousers
♦ vitals

Plurals with Singular Meanings

A few nouns are plural in form, but singular in meaning.

♦ gallows
♦ news
♦ measles
♦ mumps
♦ small pox
♦ politics

Plus, some sciences

♦ economics
♦ ethics
♦ mathematics
♦ physics

The Role of Context in Number Inflection

Context plays a huge role in how we use nouns. Depending on what you want to say, the form of a noun can change, often based on whether you’re referring to one thing or many.

♦ The fish are swimming (refers to multiple fish)
♦ The fish is fresh (refers to just one)

Contextual cues aren’t always about counting, though

♦ My glasses are broken. (refers to one set of eyeglasses)
♦ The glasses are on the table. (refers to more than one drinking glass.)

Another interesting case is with the word ‘data’.

♦ The data are conclusive. (In scientific contexts, ‘data’ is treated as plural)
♦ The data is clear  (In everyday use, it’s commonly used as a singular noun)

Context can affect other forms of a word.

♦ I read a book (uses ‘read’ pronounced as ‘red’, implying past tense)
♦ I will read a book pronounces ‘read’ as ‘reed’, showing future or present tense.

The spelling doesn’t change, but the pronunciation and meaning do, all thanks to context.

Understanding the situation you’re writing about is key because it helps you choose the right noun form.
