How to Use the Prefix and Suffix Analyzer
The Prefix and Suffix Analyzer looks for common word parts like un-, re-, -tion, and -ness attached to an English word. Type in a word and it checks it against a curated list of frequently used prefixes and suffixes, then shows you the meaning of each match along with the estimated root word left over.
English words are often built by attaching a prefix or suffix to a root to create new meaning. Take happy: add un- and you get unhappy; add -ness to that and it becomes the noun unhappiness. This tool breaks combinations like that apart so you can see exactly how a word is constructed.
Learning the common patterns behind prefixes and suffixes makes it easier to guess the rough meaning of new words you've never seen before, which speeds up vocabulary building considerably. It's a handy companion for TOEFL or TOEIC prep, or for anyone who wants to learn vocabulary systematically through etymology.
