What Are Compound Words?
Compound words are words that are created by combining two or more words together to form a new word. These words can be written as one word, using a hyphen, or as separate words. Compound words are an essential part of the English language, and they can be quite common in everyday writing and conversation. In this article, we'll explore what compound words are, how they're formed, and some examples of compound words in use.
Formation of Compound Words
Compound words are typically formed by combining two or more words that are related to each other in meaning. This can happen in several ways, including:
- By adding a prefix or suffix to a word
- By combining two words that have the same root or base
- By combining two words that have different roots or bases, but are related in meaning
For example, the compound word "bookshelf" is formed by combining the words "book" and "shelf". The word "book" refers to a bound collection of written or printed pages, while the word "shelf" refers to a horizontal surface for holding objects. When combined, these two words form a new word that refers to a piece of furniture used for storing books.

Types of Compound Words
There are several types of compound words, including:
- Open Compound Words: These are words that are written as separate words, with a space between them. Examples include "post office" and "high school".
- Closed Compound Words: These are words that are written as one word, without a space between them. Examples include "bookshelf" and "toothbrush".
- Hyphenated Compound Words: These are words that are written with a hyphen between the two words. Examples include "self-portrait" and "merry-go-round".
It's worth noting that the type of compound word can affect how it's used in a sentence. For example, the open compound word "post office" is typically used as two separate words, while the closed compound word "bookshelf" is used as one word.
