What will you learn

Nouns often take the form of compound nouns in our everyday lives. We can even spot them in literature, movies and songs. For example, Harry Potter fans may recall when in Harry Potter and the Sorcerer’s Stone, Percy, the leader of Gryffindors, led his junior to the dorm of Gryffindors. Percy says, “This is the most direct path to the dormitories. Oh, and keep an eye on the staircases; they like to change.”

The word “staircases” in the sentence above is a compound noun.

Formation of Compound Nouns: Level up your communication skills, grasp their formation techniques

Compound nouns can be formed through various combinations of word types. A straightforward breakdown of different formations is given below.

  1. Noun + Noun

In this formation, two nouns are combined to create a compound noun representing a specific concept or object. The first noun acts as a modifier or qualifier for the second noun. 

Examples:

  • Car park: A designated area for parking cars.
  • Coffee table: A low table used for serving coffee or other beverages.
  • Basketball court: A designated area for playing basketball.
  1. Adjective + Noun

When combined with a noun, an adjective forms a compound noun that describes a particular quality or characteristic of the noun. Examples include:

  • Greenhouse: A structure used for growing plants with controlled temperature and humidity.
  • Blackboard: A smooth, dark-coloured board used for writing with chalk.
  • Heavyweight: A boxer in the heaviest weight class in a sport.
  1. Verb + Noun

In this formation, a verb and a noun are combined to create a compound noun representing the object or result of the verb’s action. Examples include:

  • Breakfast: The first meal of the day, formed from the verb “break” and the noun “fast.”
  • Make-up: Cosmetics applied to enhance one’s appearance, created from the verb “make” and the noun “up.”
  • Checkout: The process of paying for items and leaving a store, formed from the verb “check” and the noun “out.”

  • Offspring: A person’s child or children, formed from the preposition “off” and the noun “spring.”

  • Bystander: a person who is present at an event but does not participate. The word is created with the adverb “by” and the noun “stander.

Usage of Compound Nouns: discover their forms, how to position them in a sentence, and tips to avoid common mistakes

Compound nouns have specific usage guidelines that govern their singular and plural forms, capitalisation, positioning in a sentence, and common mistakes to avoid. 

Singular and Plural Forms of Compound Nouns

The formation of plural forms in compound nouns depends on the specific word within the compound that indicates plurality. 

To make the plural of a compound noun, add -s to the “base word” (the most “significant” word). 

Example:

Singular

Plural

a football shoe

two football shoes 

a mother-in-law

many mothers-in-law

There are variations to the rule above, like the ones given below: 

Singular

three spoonfuls

one truckful

With compound nouns made of [noun + noun], the second noun takes an -s for plural. 

Singular

Plural

20 orange trees

a tool box

10 tool boxes

Capitalisation of Compound Nouns

  • The first word of the compound noun is always capitalised if it is used in a title or heading. The second word is also capitalised if it is not a coordinating conjunction, preposition, or article. 

Example: 

  1. The Power Hungry Politicians.
  2. The Significant Influence of Greco-Roman Art

 

  •  In closed and hyphenated compound nouns (e.g., “Mailbox” or “Mother-in-law”), 

Positioning of Compound Nouns in a Sentence

Compound nouns can function as a sentence’s subjects, objects, or modifiers. Here are some important considerations for their positioning:

Subject or Object: Compound nouns can serve as the subject or object of a sentence, just like regular nouns.

 For example

  • The coffee shop is open. (subject)
  • I visited the bookstore. (object)

Modifiers: Compound nouns can also act as modifiers for other nouns. They provide additional information or specify the type or purpose of the noun they modify.

 For example: 

  • She bought a leather jacket. (modifying “jacket”)
  • The office building is located downtown. (modifying “building”)

Frequently Asked Questions

Is a compound noun one word or two?

A compound noun is typically considered a single word formed by combining two or more words to create a new noun with its meaning.

How do you hyphenate a compound noun?

Hyphenating a compound noun involves inserting a hyphen (-) between the words that make up the compound. The hyphen connects the terms, indicating that they function together as nouns. Here are some guidelines to follow when hyphenating compound nouns:

  1. Noun + preposition: if a preposition follows the noun, we mostly place a hyphen between the two like passer-by 
  2. Noun +non-principle word+noun: these words are usually hyphenated like mother-in-law, sister-in-law 
  3. Verb + Preposition: such terms include make-up, sign-off, and build-up.

It’s important to note that not all compound nouns require hyphenation. The decision to hyphenate a compound noun depends on style guides, context, and everyday usage. Therefore, it is always advisable to consult style guides or dictionaries for specific guidelines regarding the hyphenation of compound nouns.

What is the difference between a compound noun and a regular noun?

The main difference between a compound noun and a regular noun lies in their structure and formation.

Compound Noun: It is formed by combining two or more words (nouns, adjectives, verbs, prepositions, adverbs, etc.) to create a new noun with a distinct meaning. T

Examples of compound nouns: “blackboard,” “coffee table,” “mother-in-law,” “aeroplane,” and “sunflower.”

Regular Noun: A regular noun, also known as a simple noun, is a word that represents a person, place, thing, or idea. 

Examples of regular nouns: “dog,” “book,” “city,” “happiness,” and “tree.”

Can compound nouns be plural?

Yes, compound nouns can indeed be pluralised. However, the way compound nouns are pluralised depends on their structure and the specific word within the compound that indicates plurality.

How do you capitalise compound nouns?

Capitalisation rules for compound nouns depend on the specific type of compound noun and its formation. 

The first word of the compound noun is always capitalised if it is used in a title or heading. The second word is also capitalised if it is not a coordinating conjunction, preposition, or article. 

Example: The Power Hungry Politicians.

The Significant Influence of Greco-Roman Art

  • The first letter of each word is capitalised if it starts a sentence in closed and hyphenated compound nouns (e.g., “Mailbox” or “Mother-in-law”), the first letter of each word is capitalised if it starts a sentence.
