About iRootWord: English Word Roots
iRootWord - Learn one root, unlock a whole family of words.
Tired of memorizing vocabulary that fades overnight? iRootWord uses morphology to turn scattered words into a connected knowledge map. Learn one root, and you can understand, guess, and remember an entire cluster of related words. It is an English root-and-affix dictionary and study companion, deeply integrated with Apple platforms, fully usable offline, with no ads and no tracking.
Many learners remember today and forget tomorrow, then cram before exams and start over. iRootWord takes a smarter path: master the building blocks first, then expand into related vocabulary. Once you see how roots, prefixes, and suffixes combine, long words become structures you can decode, infer, and retain.
