Nouns: Definition, Types and Examples (Common, Proper, Countable, Collective and More)

A noun is a word that names a person, place, thing, idea or quality: teacher, Manchester, laptop, honesty. English nouns fall into overlapping types: common or proper, countable or uncountable, concrete or abstract, plus collective nouns. In a sentence a noun can be the subject, an object, a complement or the object of a preposition. The trickiest area for learners is uncountable nouns such as advice, information and equipment.

What is a noun?

A noun is a word that names something: a person (nurse), a place (Toronto), a thing (kettle), an idea (freedom), an event (the election) or a quality (patience). Nouns are the words that most sentences are built around. Take them out of "The nurse gave the patient clear advice" and little is left to say.

A reliable test: if you can put "the", "a" or "some" in front of a word and the phrase still makes sense, it is probably a noun. "The kettle", "some advice" and "a decision" all pass. "The quickly" does not, because "quickly" is an adverb.

Nouns are one of the eight traditional parts of speech. For the full set, see our guide to parts of speech.

The main types of noun at a glance

English nouns can be sorted in several ways at once. One word can belong to more than one group: "Mum" is proper (when used as a name), singular and countable; "furniture" is common, concrete and uncountable.

Common and proper nouns

A common noun names a kind of thing: "university", "river", "company". A proper noun names one particular example and begins with a capital letter: "the University of Leeds", "the Thames", "Tesco". Days, months and holidays are proper nouns in English (Tuesday, October, Diwali), but seasons are not (spring, winter). Languages, nationalities and religions are capitalised too: English, Nigerian, Buddhism.

A common noun becomes part of a proper noun when it is part of a name: "the president spoke" but "President Lincoln", "my aunt" but "Aunt Sarah".

Countable and uncountable nouns

This is the distinction that causes most errors, so it has its own section below.

Collective nouns

A collective noun is singular in form but names a group: team, committee, jury, staff, family, audience, band. Whether the verb is singular or plural depends on the variety of English and on your meaning.

• American English: "The committee has decided." (treated as one unit)
• British English: "The committee have decided" is also acceptable when the members act individually.

Abstract and concrete nouns

Concrete nouns name things you can perceive: "bus", "pizza", "siren". Abstract nouns name ideas, states and qualities: "justice", "boredom", "efficiency". Many abstract nouns are made from other words by adding a suffix: kind becomes kindness, decide becomes decision, free becomes freedom, deliver becomes delivery.

How nouns work in a sentence

A noun does a job in the sentence. The same word can do different jobs in different sentences.

When a noun is the subject, the verb must agree with it in number. When two or more nouns are joined by "and", the subject is usually plural: "The manager and the intern are travelling together."

Noun phrases

Nouns rarely appear alone. A noun phrase is a noun plus the words that describe it: "the new office", "a very long email", "several students from the evening class". The noun at the centre is called the head. Articles, adjectives and prepositional phrases all attach to it. For more on the describing words, see adjectives.

Plural nouns: the quick rules

Most countable nouns add -s (book, books). The main exceptions are worth knowing:

A fuller treatment is in the guide to plural nouns. For possessives such as "the manager's office" and "the managers' office", see apostrophe rules.

The uncountable noun trap

Uncountable (or mass) nouns name things treated as an undivided mass. They have no plural form, do not take "a/an", and take a singular verb. Learners whose first language counts these nouns differently often write them as plurals, and so do many native speakers under pressure.

Common uncountable nouns that are often mistaken for countable ones:

How to count an uncountable noun

You cannot say "two advices", but you can count a unit of the thing:

• a piece of advice, two pieces of information
• an item of furniture, a piece of equipment
• a bit of news, a word of warning
• a cup of coffee, a loaf of bread, a bar of soap

Quantity words: much, many, a lot of

Use "many" and "few" with countable nouns, "much" and "little" with uncountable nouns. "A lot of" and "some" work with both.

• Countable: many suggestions, a few books, fewer mistakes
• Uncountable: much advice, a little time, less money

In everyday British and American speech, "less" is often used with countable nouns ("less mistakes"). Formal writing and most style guides prefer "fewer mistakes".

Nouns that can be both

Some nouns are countable in one meaning and uncountable in another. "Paper" is uncountable when it means the material ("a sheet of paper") and countable when it means an essay or a newspaper ("three papers to mark", "the morning papers"). Likewise "time" (uncountable: "I don't have much time"; countable: "three times"), "work" (uncountable: "I have work to do"; countable: "the works of Dickens") and "experience" (uncountable: "ten years of experience"; countable: "a memorable experience").

Common noun mistakes

1. Pluralising uncountable nouns. "Advices", "informations", "equipments" are not standard English.
2. Missing capitals on proper nouns. "i study in london" should be "I study in London".
3. Capitalising common nouns for emphasis. "Our Company values Quality" is out of style in modern English; capitalise only proper nouns.
4. Wrong verb agreement with collective nouns. Do not switch between "the team is" and "the team are" in the same paragraph.
5. Using a plural verb with "news" or subject names such as "mathematics". These end in -s but are singular: "The news is good."
6. Confusing plural and possessive. "The students books" should be "the students' books"; "Two dog's" should be "Two dogs".
7. Nouns used as verbs unnecessarily. "Let's action this" is workplace jargon; prefer "Let's act on this" in careful writing.

Quick checklist for editing nouns

• Is every proper noun capitalised, and every common noun not?
• Have I used a plural form only for countable nouns?
• Does each verb agree with its noun subject, including collective nouns?
• Are apostrophes used for possession and not for plurals?
• Could a vague noun such as "thing", "stuff" or "factor" be replaced with a precise one?
