Etyma 词根词缀背单词

Say goodbye to rote memorization. Break down words using roots and affixes, understand their origins, and remember them more firmly and for longer. ¥6 one-time purchase, lifetime access.

Etyma is an app that helps you remember English words through etymology. By learning roots and affixes, you can: deduce the meanings of new words from their components, spell correctly by memorizing morphemes, and make fewer spelling errors—instead of memorizing letter by letter. Once you understand components like spect (see), port (carry), and vis (see), hundreds of derived words will no longer seem unfamiliar.

■ Why start with roots and affixes

· Understand meanings – When encountering unknown words, break them into roots and affixes to grasp the general meaning.
· Spell correctly – Memorize using “blocks” like in + spect, which is more effective than rote letter-by-letter memorization.
· Reduce spelling mistakes – Understanding patterns such as -tion/-sion or ad- assimilation naturally helps avoid common spelling errors.
