ROOT FINDER 85 prefixes, 1,486 roots and 322 suffixes. Look up a root to see every term that uses it, or open any term to see how it is built. Meet a new word, break it down, and you can usually guess it. AI BREAKDOWN Any medical term outside the library: type it and AI breaks it into roots with a definition, memory tip, related words and an example, in about 10 seconds, in your language. MY WORD BOOKS Paste a word list from your textbook, lecture notes or exam syllabus. Terms in the library get the curated card; the rest are generated by AI.
