Compound Words: Definition and Examples Explained 1

What are compound words?

Compound words are words formed by the union of two or more simple words that retain their individual meanings. These words usually have a semantic relationship between their components, which allows us to understand their meaning as a whole.

Types of Compound Words in English with Examples

1. Closed Compound Words

Closed compound words are formed when two unique words are combined to create a new meaning, and they appear as a single word. These are prevalent in English and are often used in everyday language.

Examples:

- Notebook (note + book): A book with blank pages for writing notes.
- Sunflower (sun + flower): A plant known for its large flower heads that turn toward the sun.
- Keyboard (key + board): A set of keys for operating a computer or typewriter.

2. Open Compound Words

Open compounds are written as separate words but, when used together, represent a single item or concept. These are sometimes harder to recognize as compound words due to their appearance.

Examples:

- Full moon (full + moon): The phase of the moon when it is fully illuminated.
- Living room (living + room): A room in a residence used for common social activities.
- Post office (post + office): A public department that handles mail and postage.

3. Hyphenated Compound Words

Hyphenated compounds are two or more words that are connected by one or more hyphens. They often arise when modifying phrases come before nouns, or when the compound word itself is formed from multiple parts.

Examples:

- Mother-in-law (mother + in + law): The mother of one's spouse.
- Well-being (well + being): The state of being comfortable, healthy, or happy.
- Long-term (long + term): Involving, maturing over, or remaining for a long time.

4. Compound Nouns

A subcategory of compound words, compound nouns combine two or more words to create a new noun. They can be closed, open, or hyphenated.

Examples:

- Toothbrush (tooth + brush): A brush for cleaning teeth.
- Ice cream (ice + cream): A frozen sweet dessert made from cream or milk and sugar.
- Brother-in-law (brother + in + law): The brother of one's spouse or the husband of one's sibling.

5. Compound Adjectives

These are adjectives consisting of two or more words and often come with hyphens. They provide a unique way to describe objects and situations.

Examples:

- High-speed (high + speed): Operating at, capable of, or involving high speed.
- Old-fashioned (old + fashioned): In the style of an earlier period.
- English-speaking (English + speaking): Able to speak English.
