what is a compound word noun
What is a Compound Noun. Compound nouns are words for people, animals, places, things, or ideas, made up of two or more words. Most compound nouns are made with nouns that have been modified by adjectives or other nouns. In many compound nouns, the first word describes or modifies the second word, giving us insight into what kind of thing an item is, or providing us with clues about the itemâs purpose. The second word usually identifies the item. Compound nouns are sometimes one word, like toothpaste, haircut, or bedroom.
