What is a compound noun?
A compound noun is a type of noun that is formed by combining two or more words together to create a new word with a unique meaning. Compound nouns can be made up of different types of words, including nouns, adjectives, verbs, and other parts of speech. The combined words work together to create a single noun that represents a specific concept, object, place, person, or idea.
They can be written as a single word (closed compound), hyphenated (hyphenated compound), or as separate words (open compound). For example, “sunflower” is a closed compound noun, “well-known” is a hyphenated compound noun, and “ice cream” is an open compound noun.
Definition of the compound noun
According to Collins Dictionary, a compound noun is a noun that is formed from two or more words. The meaning of the whole compound is often different from the meaning of the two words on their own. Oxford Learners Dictionaries defines, a noun as an adjective or a verb made of two or more words or parts of words, written as one or more words, or joined by a hyphen. Travel agent, dark-haired and bathroom are all compounds.
Types of Compound Nouns
Compound nouns can be classified into different types based on their formation and structure. Here are some common types of compound nouns:
1. Closed compound nouns: In this formation, two or more words are combined to create a single word without any spaces or hyphens.
For example:
butterfly, baseball, football, bookshelf, watermelon.
2. Hyphenated compound nouns: In this type, two or more words are combined with hyphens to create a compound noun. This is often done to clarify the meaning or to indicate that the words are closely related. For example: mother-in-law, self-esteem, jack-o’-lantern, six-pack, up-to-date.
3. Open compound nouns: In this noun, two or more words are combined, but they are written as separate words without any hyphens.
For example:
ice cream, high school, post office, new year, coffee table.
It’s important to note that not all combinations of words result in a compound noun. Some combinations may be considered phrases or expressions rather than compound nouns. Compound nouns typically have a specific meaning that is different from the meanings of the individual words used to form them, and their meaning is often not predictable from the meanings of the individual words alone.

Rules for compound nouns
There are several rules to keep in mind when it comes to compound nouns in English. Here are some general guidelines:
1. Forming Compound Nouns: Compound nouns can be formed by combining two or more words from different word classes, such as nouns, adjectives, verbs, and adverbs. The words are combined together to create a single concept or idea. Compound nouns can be formed in three main ways:
- Closed or Solid Compound Nouns: These compound nouns are written as a single word without any spaces or hyphens between the component words, e.g., butterfly, baseball, and cupcake.
- Hyphenated Compound Nouns: These compound nouns are formed by connecting the component words with hyphens (-), e.g., mother-in-law, well-being, and high-speed.
- Open Compound Nouns: These compound nouns are written as separate words without any hyphens or spaces between the component words, e.g., ice cream, football field, swimming pool.
2. Word Order: In compound nouns, the most important or defining word usually comes first, followed by the word that modifies or describes it. For example, “car wash” is a compound noun where “car” is the main or defining word, and “wash” is the modifier or descriptor.
3. Plural and Possessive Forms: In compound nouns, the plural and possessive forms are generally applied to the main or defining word, while the modifier or descriptor remains unchanged. For example, “brothers-in-law” is the plural form of “brother-in-law”.
4. Consistency in Usage: It’s important to maintain consistency in the usage of compound nouns throughout your writing or communication. Once you choose a certain form (closed, hyphenated, or open), it’s best to stick with that form throughout your text, unless there are specific style guides or language conventions that dictate otherwise.

Compound noun:
- A compound noun is a single noun that is formed by combining two or more words together to create a new noun with a specific meaning.
- Compound nouns are typically written as a single word (e.g., “laptop,” “sunflower,” “firefighter”) or with hyphens (e.g., “well-being,” “mother-in-law”) or as separate words (e.g., “post office,” “time management”) depending on the type of compound noun.

Noun phrase:
- A noun phrase is a group of words that includes a noun and other words that modify or provide additional information about the noun.
- Noun phrases can be simple (e.g., “the book,” “a cat”) or complex (e.g., “the big red ball,” “an old wooden chair”).
- Noun phrases can include determiners (e.g., articles, possessive pronouns), adjectives, and/or other modifiers that provide more context or description to the noun.
- Noun phrases can function as subjects, objects, or complements in a sentence, and they may or may not have a specific meaning beyond their individual words depending on the context in which they are used.
