Also known as: composition

Quick Summary

In grammar, compounding refers to the process of combining two or more words to create a new word with a distinct meaning. These new words, known as compound words, can be written as a single word (e.g., haircut), hyphenated (e.g., high-speed), or as separate words (e.g., health care).1

The meaning of a compound word is often derived from its components, with one word typically modifying the other. For instance, in "chain saw," "saw" is the main word, and "chain" specifies the type of saw. Compound words can function as nouns, adjectives, or verbs, depending on the part of speech of their main component. The formation of compound words can sometimes lead to confusion in spelling, as words that seem similar might be written differently depending on their grammatical function.12
