Nouns can be classified into various types. While noun as a single concept is very simple, its classifications require a little more attention.
Common nouns, concrete nouns, compounds nouns, etc., are all different types of nouns. Today we will discuss compound nouns. Compound nouns can be a little tricky if some rules are not followed.
Compound nouns are basically the combination of two words. It is an easy concept, but some points need to be kept in mind.
What is a compound noun?
A compound noun is a noun formed by joining two or more words together. It is a combination of words that refers to a person, thing, or place.
In a compound noun, the first word basically describes the second word. It describes the purpose or type of the second word and the second word is usually the identification of the first word. It tries to tell what or who is the first word.
Let us understand with some examples;
- Lighthouse
- Firehouse
- Honeybee
Here, we can see that the first word is the description or modification of the second word and the second word basically tells what is being named.
Different types of a compound noun
Compound nouns are two words joined together. However, they can be formed in usually three different ways.
Let us understand with basic examples;
First is a closed-form compound noun. Here, the compound nouns are joined together normally.
- I am visiting the lighthouse today.
- There is a housefly in the car.
Some compound nouns can be a word in a hyphenated form. They are presented with hyphens.
- My mother-in-law is at home.
And the third form is where the words are presented as two individual words, but they are a single entity.
- I think he is visiting the post office today.
Formation of compound nouns
There are several ways of forming a compound noun. Any part of speech can act as a term to make a compound noun. Let us discuss them in detail;
A compound noun can be formed by joining two nouns together.
For example;
- wallpaper
- birdcage
- honeymoon
- lighthouse
A noun and an adjective
For example;
- Wireless
- handful
- headless
An adjective and a noun
For example;
- pink panther
- redhead
- full moon
A preposition and a noun
For example;
- past lives
- afterlife
- underworld
A noun and a preposition or a prepositional phrase
For example;
- passer-by
- Father-in-law
A verb and a noun
For example;
- washing machine
- swimming pool
- dressing room
- waiting room
A noun and a verb
For example;
- photoshoot
- sunrise
- haircut
- hairstyle
An adjective and an adjective
For example;
- pinkish-yellow
- reddish-brown
These are the major ways of forming a compound noun. However, there can be more, such as preposition+verb, Verb+preposition, etc. As mentioned earlier, it can be any part of speech.
So we see compound nouns can be wide. Compound nouns also depend on the context they are being used in.
They are not just any combination of words. One has to be careful while using a compound noun to avoid any errors.
Last night, I took my roommate to a drive-in to see the latest blockbuster. It was a fun night, but it was also an example of an event that can be described with nouns. Not just any nouns, though. We use many different types of nouns to refer to people we love, places we take them, and things we enjoy together, but my story uses a couple examples of one particular type of noun: the compound noun.
What is a compound noun?
In grammar, a compound refers to a word that is made up of two or more existing parts or elements. Adjectives, verbs, prepositions, and nouns can all be described as compounds.
As compounds, they are made of two or more existing words combined into one, such as housetop (noun), many-sided (adjective), playact (verb), or upon (preposition).
A compound noun, in simplified terms, is a noun made up of two or more existing words. They are extremely common in English. The word snowstorm is an example of a simple type of compound noun formed from the words snow and storm. Compound nouns aren’t just formed from nouns but other types of words as well, such as verbs, adjectives, and prepositions. You can see this in words like runoff, takedown, and shortcake.
One main thing to keep in mind about compound nouns is that they have a meaning that is distinct from their component parts. For example, a blackboard is an object that a teacher writes on with chalk while a “black board” is any black piece of wood.

Compound noun examples
In English, there are three main ways that we form compound nouns. As is often the case in English, there is no single rule that states which of these methods is correct when it comes to forming specific compound nouns. You will either need to memorize compound nouns as you come across them or use our fantastic dictionary to see which form (or forms) should be used.
Compound nouns as a single word
This type of compound noun is formed by combining two words (from different parts of speech) together into a single word. Here are examples of compound nouns formed from pairs of different types of words:
- Noun + noun: lunchtime, boyfriend, milkman, firefighter, hatrack, heartache
- Verb + noun: jailbreak, haircut, runtime, turntable, sweatshirt, buzzkill
- Adjective + noun: smartphone, bluebird, redhead, greenhouse
- Preposition + noun: downtown, bystander, underworld, overtime
- Verb + preposition: breakdown, offshoot, downturn, input, uproar
Compound nouns as separate words
This type of compound noun is formed by using two separate words together that are acting together, grammatically, as a single unit. This type of compound noun is different from a noun phrase because one word isn’t acting as a modifier of another. You need to be careful with this type of compound noun as they may look identical to an instance of two separate words that aren’t being used as a compound noun. For example, the compound noun hot dog refers to a food while the separate words “hot dog” refers to a hairy animal that is very warm (and a good boy).
- Noun + noun: house party, grandfather clock, sweater vest, Christmas tree
- Verb + noun: flash flood, grab bag, jump cut, slam dunk, shock jock
- Adjective + noun: quick fix, easy money, slow burn, double agent, close call
Compound nouns with hyphens
This type of compound noun is often confused with the other two types. Using hyphens to form compound nouns is particularly common in newer or rarely used words. If a compound noun is formed from more than two words, it will almost always use hyphens.
- know-it-all, mother-in-law, show-off, court-martial, jack-in-the-box, jack-of-all-trades, Johnny-come-lately, city-state, hocus-pocus, merry-go-round
Plural forms of compound nouns
Until now, we have only looked at singular nouns. However, there are different rules about how to make compound nouns into plural nouns depending on which of the three types you are dealing with.
Plural of single-word compound nouns
Of the three, this type of compound noun is the most likely to follow the rules of plural nouns. You can take a look at our article on plural nouns if you need a refresher, but the usual method is to add -s or -es to the end of the compound noun. For example, chalkboard becomes chalkboards and eyelash becomes eyelashes.
Plural of multiple-word compound nouns
This type of compound noun gets more complicated. Sometimes, these words stick to the rules, and all you need to do is make the last word plural as in wedding planners or soft drinks. However, things can get more complicated. For example, the plural of attorney general is attorneys general. The reason is that the word attorney is acting as the main word and general is specifying what job the attorney has. In this case, it makes more sense to turn attorney into a plural when referring to more than one attorney general. Keep this in mind as we look at our last type of compound noun.
Plural of compound nouns with hyphens
Once again, things get complicated. Sometimes, hyphenated compound nouns follow the rules and get an -s or -es added onto the last word as in jack-in-the-boxes or fixer-uppers. Other times, though, hyphenated compound nouns don’t follow the pattern as in sisters-in-law or runners-up. As was the case in multiple-word compound nouns, these words turn the main word rather than the final word into a plural.
List of compound nouns
Let’s look at more examples of compound nouns. As you read each of these nouns, think about what words were used to form them and how the meanings of these nouns differ from the words used to make them.
- artwork, basketball, card shark, double dip, earmark, fast track, gold rush, half-and-half, icebreaker, junk mail, kangaroo court, ladybug, mother-of-pearl, night-light, odd-job, post office, queen bee, riverbank, small fry, think tank, upperclassmen, victory lap, whiz kid, yardstick, zookeeper
The difference between compound & collective nouns
Up until now, we have looked at many different examples of compound nouns. Compound nouns are formed by combining multiple words together to make a single noun. Another type of noun also brings several things together to form a single noun. A collective noun is a noun that collectively refers to multiple people or objects as a single entity. The words army, gang, pile, stack, group, and bunch are all examples of collective nouns. Unlike compound nouns, collective nouns don’t need to be formed from multiple words.
For the most part, both compound nouns and collective nouns follow the rules that all other nouns follow. Both can be singular nouns or plural nouns. Both can be concrete nouns or abstract nouns. Both can be possessive nouns.
Try another noun on for size, and see what you know about proper nouns.
Although rare, it is possible for a noun to be both a compound noun and a collective noun. For example, the word homeroom is a compound noun formed from the words home and room. At the same time, homeroom can be used as a collective noun to refer to a group of students.
Take a look at some example sentences. Read each sentence and see if you can understand what makes each given noun a compound noun, a collective noun, or both.
- I can’t handle the heartbreak of losing a pet.
- Our team won the championship.
- Two of my friends are members of the glee club.
- The goblin kingdom crumbled due to a civil war.
- The cruel billionaire looked down on the lower class.

В английском языке три типа compound nouns — составных или сложных существительных: open (части которого пишутся раздельно), hyphenated (части которого пишутся через один дефис или более) и closed (части которого пишутся слитно, единым словом).
Сложные существительные образуются постоянно по мере того, как движется мир вокруг нас, а с ним и технический прогресс, и многие когда-то были сначала сложными существительными, которые писались раздельно, затем через дефис, и наконец, уже слитно. Учитывая современную тенденцию избегать по мере возможности написания сложных слов через дефис, заново изобретаемые сложные существительные быстрее достигают слитного написания, чем когда-то раньше. Некоторые сложные существительные, которые в США пишутся слитно, одним словом, в Британском английском пишутся через дефис.
10 способов образовать сложное /составное существительное
Сложные существительные образуются при помощи комбинирования различных частей речи, и нижеследующий перечень из десяти способов не является самым полным.
- Существительное + существительное
- Wheeler +dealer = wheeler-dealer – махинатор, пройдоха
- Bed+room= bedroom – спальня
- Shoe+lace= shoelace – шнурки
- Существительное + предлог/наречие
- hanger+on = hanger-on – навязчивый поклонник
- voice+over = voice-over – голос за кадром
- passer + by = passerby (Британский англ. passer-by) – прохожий
- Существительное + прилагательное
- attorney + general= attorney general – министр юстиции/генеральный прокурор
- battle + royal = battle royal – общая свалка, генеральное сражение
- poet + laureate = poet laureate – поэт-лауреат
- Существительное + глагол
- Air+lift = airlift – воздушные перевозки
- Hair+cut = haircut – стрижка
- Snow+fall= snowfall – снегопад
- Прилагательное + существительное
- high + school = high school – средняя школа, гимназия
- poor+ loser = poor loser – лузер, проигрывающий
- red+head = redhead – рыжий, рыжеволосый
- Прилагательное + причастие
- Well+being = well-being – благополучие
- White+washing = whitewashing – побелка
- Предлог / наречие + существительное
- Off+ramp = off-ramp – съезд
- On+looker = onlooker – зритель, наблюдатель
- Причастие + существительное
- singing + lesson = singing lesson – урок пения
- washing + machine = washing machine – стиральная машина
- Глагол + предлог/наречие
- Warm+up = warm-up – прогрев
- Know+how = know-how – умение, опыт
- Get+together = get-together – вечеринка, собрание
- Follow +through = follow-through – оправдывать ожидания
- Слово + предлог + слово
- Free+for + all = free-for-all – свалка, потасовка
- Mother +in+law = mother-in-law – свекровь, теща
- Word+of+mouth = word-of-mouth – из уст в уста
Большинство сложных существительных образуют свои формы множественного числа таким же способом, как и другие существительные – прибавлением окончания «-s/-es» к слову, например: onlookers, washing machines, wheeler-dealers.
Только некоторые, такие как mother-in-law и hole in one принимают окончание «-s/-es» к первому слову: holes in one, mothers-in-law.
Некоторые сложные существительные французского происхождения, в которых последним словом является прилагательные, образуют формы множественного числа по-разному, и их нужно проверять по словарю. Возможно даже, что окончание «-s/-es» будет применено к обеим частям сложного существительного, или будут допускаться разные формы:
- attorney generals или attorneys general
- court martials или courts martial
- film noirs, films noirs или films noir
- runner-ups или runners-up
A compound noun is a noun that is made with two or more words. A compound noun is usually [noun + noun] or [adjective + noun], but there are other combinations (see below). It is important to understand and recognize compound nouns. Each compound noun acts as a single unit and can be modified by adjectives and other nouns.
There are three forms for compound nouns:
- open or spaced — space between words (tennis shoe)
- hyphenated — hyphen between words (six-pack)
- closed or solid — no space or hyphen between words (bedroom)
Here are some examples of compound nouns:
noun | + | noun | bus stop | Is this the bus stop for the number 12 bus? |
---|---|---|---|---|
fire-fly | In the tropics you can see fire-flies at night. | |||
football | Shall we play football today? | |||
adjective | + | noun | full moon | I always feel crazy at full moon. |
blackboard | Clean the blackboard please. | |||
software | I can’t install this software on my PC. | |||
verb(-ing) | + | noun | breakfast | We always eat breakfast at 8am. |
washing machine | Put the clothes in the red washing machine. | |||
swimming pool | What a beautiful swimming pool! | |||
noun | + | verb(-ing) | sunrise | I like to get up at sunrise. |
haircut | You need a haircut. | |||
train-spotting | His hobby is train-spotting. | |||
verb | + | preposition | check-out | Please remember that check-out is at 12 noon. |
noun | + | prepositional phrase | mother-in-law | My mother-in-law lives with us. |
preposition | + | noun | underworld | Do you think the police accept money from the underworld? |
noun | + | adjective | truckful | We need 10 truckfuls of bricks. |
Pronunciation
Compound nouns tend to have more stress on the first word. In the phrase «pink ball», both words are equally stressed (as you know, adjectives and nouns are always stressed). In the compound noun «golf ball», the first word is stressed more (even though both words are nouns, and nouns are always stressed). Since «golf ball» is a compound noun we consider it as a single noun and so it has a single main stress — on the first word. Stress is important in compound nouns. For example, it helps us know if somebody said «a GREEN HOUSE» (a house which is painted green) or «a GREENhouse» (a building made of glass for growing plants inside).
British/American differences
Different varieties of English, and even different writers, may use the open, hyphenated or closed form for the same compound noun. It is partly a matter of style. There are no definite rules. For example we can find:
- container ship
- container-ship
- containership
If you are not sure which form to use, please check in a good dictionary.
Plural Forms of Compound Nouns
In general we make the plural of a compound noun by adding -s to the «base word» (the most «significant» word). Look at these examples:
singular | plural |
---|---|
a tennis shoe | three tennis shoes |
one assistant headmaster | five assistant headmasters |
the sergeant major | some sergeants major |
a mother-in-law | two mothers-in-law |
an assistant secretary of state | three assistant secretaries of state |
my toothbrush | our toothbrushes |
a woman-doctor | four women-doctors |
a doctor of philosophy | two doctors of philosophy |
a passerby, a passer-by | two passersby, two passers-by |
Note that there is some variation with words like spoonful or truckful. The old style was to say spoonsful or trucksful for the plural. Today it is more usual to say spoonfuls or truckfuls. Both the old style (spoonsful) and the new style (spoonfuls) are normally acceptable, but you should be consistent in your choice. Here are some examples:
old style plural (very formal) |
new style plural | |
---|---|---|
teaspoonful | 3 teaspoonsful of sugar | 3 teaspoonfuls of sugar |
truckful | 5 trucksful of sand | 5 truckfuls of sand |
bucketful | 2 bucketsful of water | 2 bucketfuls of water |
cupful | 4 cupsful of rice | 4 cupfuls of rice |
Some compound nouns have no obvious base word and you may need to consult a dictionary to find the plural:
- higher-ups
- also-rans
- go-betweens
- has-beens
- good-for-nothings
- grown-ups
Note that with compound nouns made of [noun + noun] the first noun is like an adjective and therefore does not usually take an -s. A tree that has apples has many apples, but we say an apple tree, not apples tree; matchbox not matchesbox; toothbrush not teethbrush.
With compound nouns made of [noun + noun] the second noun takes an -s for plural. The first noun acts like an adjective and as you know, adjectives in English are invariable. Look at these examples:
long plural form becomes → | plural compound noun [noun + noun] |
---|---|
100 trees with apples | 100 apple trees |
1,000 cables for telephones | 1,000 telephone cables |
20 boxes for tools | 20 tool boxes |
10 stops for buses | 10 bus stops |
4,000 wheels for cars | 4,000 car wheels |
