Prefixes & Suffixes
Prefixes and suffixes are small word parts added to the beginning or end of a root word to change its meaning or its grammatical role. A prefix such as un- in unhappy can reverse a word's sense, while a suffix like -ness in kindness can turn an adjective into a noun. Because these additions work quietly behind the scenes, they are one of the simplest ways to build a richer vocabulary and to see how many English words are connected. Once you start noticing them, words that once looked unfamiliar often become easier to decode.
Understanding prefixes and suffixes matters because it helps you read more accurately, choose words more precisely, and speak with greater confidence. They can show whether a word is negative, plural, comparative, or related to a particular field, which makes them useful in both everyday communication and more formal writing. On this page, you can explore common patterns, check meanings, and learn how word endings and beginnings affect spelling and usage. Use it to spot familiar parts in new words, strengthen your word-building skills, and gradually make your English more natural, flexible, and exact.
