The English language is full of words that are created by joining two or more smaller words together. These are called compound words. They are an essential part of everyday communication, making language more descriptive, creative, and precise.Â
In this article, you will learn what compound words are, their types, how they are formed, and how to use them correctly in your writing and speaking.
A compound word is a word formed when two or more separate words are combined to create a new word with a specific meaning. The meaning of the compound word is usually different from the meanings of its individual words.
Examples:
- Tooth + brush = Toothbrush
- Rain + coat = Raincoat
Compound words can appear as a single word, with a hyphen, or as separate words.
