Etyma: Word Roots & Vocabulary

Note: the app interface is available in English, while word explanations, definitions and example translations are in Simplified Chinese. Etyma helps you learn English words through etymology. Master roots and affixes and you'll decode the meaning of new words, spell them correctly by their parts, and make fewer spelling mistakes — instead of memorizing letter by letter. Once you grasp building blocks like spect (to see), port (to carry), and vis (to see), hundreds of derived words fall into place. ■ Why start from roots & affixes · Decode meaning — break a new word into its parts and infer what it means. · Spell it right — remembering chunks like in + spect sticks better than letter-by-letter. · Fewer mistakes — knowing patterns like -tion / -sion and ad- assimilation helps you avoid common misspellings. ■ Features · Roots & Affixes Library Roots and affixes organized by origin (Latin, Greek, Old English, French and more), each with meaning, IPA, etymology, mnemonics and derived words. · Smart Decomposition Type any word and see it broken into root + affixes to understand how it's built. · Spaced Repetition Reviews scheduled by the SM-2 algorithm, reminding you right before you forget for maximum efficiency. · Daily Challenge Ten questions a day across four formats to reinforce and test your mastery. · Etymology Reading Meet the roots you've learned in real context — highlighted and tappable for instant breakdown. · Stats & Achievements A 28-day heatmap, origin distribution, day streaks and 12 achievements make progress visible. · Mistake Bank Wrong answers are collected automatically; answer correctly twice in a row to graduate them. ■ Pricing 7-day free trial of all features.
