Compound Words
Compound words are two little words which are put together to make one larger word. The large word retains the original meanings of the small words – it’s just more expressive and less wieldy than using the words separately.
The really cool thing about compound words is that they’re flexible and changeable. If you find yourself in desperate need of a word which doesn’t exist in English, you’re able to make one up and call it a compound word.
There are three varieties of compound words: closed, hyphenated, and open.
