About this app

Vocabulary is essential for improving your English.
Instead of memorizing words one by one, learning them through roots helps you remember them more efficiently.
When you understand prefixes, roots, and suffixes, it becomes easier to guess the meaning of new English words.

For example, write inject and Roots can break it down into in, meaning “into,” and ject, meaning “throw.”
The image of “throwing into” makes the meaning of inject easier to remember.

Roots is an English vocabulary app that creates a wordbook with etymology and example sentences from the words you want to learn.

Words and example sentences include audio.
Listen and shadow the sentences as many times as you need, so you can learn pronunciation, meaning, and usage together.

Learn English words with clear audio and memorable roots.

Review saved words with flashcards.
Record whether you remember each word and manage what you need to review next.
Understand words through roots, check usage with examples, and strengthen memory with flashcards.

Track words learned every day
