A compound word is a word that is formed by combining two or more separate words. There are a few different types of compound words:
* Closed compounds: These words are written as one word, like "rainbow" (rain + bow).
* Hyphenated compounds: These words are written with a hyphen between the words, like "well-being" (well + being).
* Open compounds: These words are written as separate words, like "high school" (high + school).
Examples of compound words:
* Closed: sunrise, butterfly, football
* Hyphenated: self-esteem, well-known, one-sided
* Open: living room, full moon, ice cream
