What Are Compound Nouns?
Compound nouns in English grammar are nouns created when two or more words are joined together to form one specific meaning. These can appear as single words, hyphenated terms, or open (separate word) forms.
Types of Compound Nouns
There are three main types of compound nouns. Knowing the differences helps you use them correctly in classwork, creative writing, and everyday English.
- Closed or Solid Compound Nouns: Written as a single word (e.g., classroom, notebook, sunflower).
- Hyphenated Compound Nouns: Words joined with hyphens (e.g., mother-in-law, editor-in-chief).
- Open or Spaced Compound Nouns: Written as separate words (e.g., bus stop, post office).
Type | Examples |
---|---|
Closed | notebook, toothpaste, classroom, playground |
Hyphenated | mother-in-law, passer-by, well-being |
Open | bus stop, swimming pool, coffee table |
Formation and Rules of Compound Nouns
Compound nouns can be made by joining different parts of speech, but usually at least one is a noun. The most common combinations are noun + noun, adjective + noun, verb + noun, or noun + preposition.
- Most compound nouns are formed using noun + noun (e.g., football, bedroom).
- Some use adjective + noun (e.g., greenhouse, full moon).
- Others use verb + noun (e.g., washing machine, swimming pool).
- The main (head) word determines plural form and meaning.
Compound Noun | Plural Form |
---|---|
bus stop | bus stops |
mother-in-law | mothers-in-law |
swimming pool | swimming pools |

Compound Nouns vs. Compound Words and Noun Phrases
All compound nouns are compound words, but not all compound words are nouns. For example, “high-speed” is a compound adjective, and “take off” is a compound verb. Compound nouns name people, things, or places as single units.
- Compound noun: toothpaste (thing)
- Compound adjective: well-known (describes someone/something)
- Noun phrase: “the tall boy” (article + adjective + noun)

FAQs on Compound Nouns in English Grammar: Meaning, Types & Examples
1. What is a compound noun?
A compound noun is a noun formed by combining two or more words. These words create a single noun with a specific meaning, different from the individual words' meanings. For example, toothbrush combines "tooth" and "brush" to represent a tool for cleaning teeth.
2. What are the types of compound nouns?
There are three main types:
• Closed compound nouns: Written as one word (e.g., sunbeam, classroom).
• Open compound nouns (or spaced compound nouns): Written as two separate words (e.g., bus stop, ice cream).
• Hyphenated compound nouns: Written with a hyphen (e.g., mother-in-law, check-in).
3. How are compound nouns formed?
Compound nouns are formed by combining different parts of speech, usually nouns, adjectives, verbs, or prepositions. The most common combinations are noun + noun (sunbeam), adjective + noun (blackboard), and verb + noun (washing machine). The specific combination impacts the meaning and spelling.
4. How do you pluralize compound nouns?
Pluralization depends on the type of compound noun. Usually, add -s to the main word:
• Bus stops (open compound)
• Classrooms (closed compound)
• Mothers-in-law (hyphenated compound). However, there are exceptions, so always check a dictionary.
5. What is the difference between compound nouns and compound words?
All compound nouns are compound words, but not all compound words are nouns. Compound words combine multiple words into a single unit, but they can function as nouns, adjectives, verbs, or adverbs. For example, check-in (noun), check-in counter (noun phrase including a compound noun), and well-behaved (adjective) are all compound words.
