Compound words are formed when two or more words are put together to form a new word with a new meaning. They can function as different parts of speech, which can dictate what form the compound takes on. For example, the word carry over is an open compound word when it’s used as a verb but it is closed when used as a noun and an a adjective.
here are some examples:
Rocketship
footprints
railroads
earthquake
sunflower
moonlight
sidewalk
nowhere
elsewhere
somewhere
lifetime
today
