What Is a Compound Word?
A compound word merges two or more root words into a new and different word. There are three kinds of compound words:- Open compound words — These have a space between the words, such as school bus or living room.
- Closed compound words — These have no spaces between them, such as classroom or homework.
- Hyphenated compound words — These have — you guessed it — hyphens between the words, such as dry-erase or forty-four.
