Stop rote memorization. Break words into roots and affixes, understand where each word comes from, and remember it for good. One-time unlock, yours forever.
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

Developer Response
Thank you so much! We're glad Etyma helps you see how words connect through their roots.More words and features are on the way — feel free to tell us what you'd like to see next.
2.1 puts words back where they're actually used.
· Scene English — 285 real-life scenes: airports, cafés, hospitals, job interviews. Each scene comes with a visual map, grouped dialogues, and short readings, and every word in it opens to its root breakdown. You learn when a word gets used, not just what it means.
· Examples grouped by sense — when a word carries several meanings, its examples are now split into groups, each labeled with the sense it illustrates. No more guessing which sentence goes with which meaning.
· Fuller Chinese definitions — senses split out for 3,934 polysemous words (9,141 senses in all), each tagged with its part of speech.
· Sharper breakdowns — a letter absorbed by the preceding part now shows as a superscript (expect = ex- + (s)pect); fragments that belong to no morpheme explain why they are there instead of being forced into one; parts of speech are unified as n. / adj.
· Make it yours — a new Paper theme with 11 accent colors, plus a full custom palette editor.
· Nothing lost on a new phone — word-family practice and quiz records now sync via iCloud.
· Smoother to use — jump back to the top of any long list; long-press the app icon for Today / Review / Decode / Daily Challenge; lookup keeps a browsing history; shake anywhere to send the developer a note.
· English definitions are now optional — word details no longer show them by default, keeping the page cleaner. Turn them back on anytime under Me > Show English definitions.
