Nouns Questions Medium
Compound nouns are formed by combining two or more words to create a single noun that represents a new concept or idea. These words can be joined together with a hyphen, without a space, or as separate words. Compound nouns can be made up of different combinations such as noun + noun (e.g., bookshelf), adjective + noun (e.g., blackboard), verb + noun (e.g., brainstorm), or preposition + noun (e.g., outfield). They can also be formed by combining a noun with a gerund or a participle (e.g., swimming pool, running shoes). Compound nouns are used to describe specific objects, places, or concepts and are an important part of the English language.
