About this app

WordDefiner is the ultimate online English dictionary and thesaurus app for Android with Material design. Learn the phonetic/phonemic transcription, pronunciation audio, and meanings, including synonyms and antonyms, based on part(s) speech for words that you look up with WordDefiner. Not just that, but you can also see statistically associated, similarly spelled, similar-sounding, and rhyming words according to your query — even if the definition of your query can't be found. If that's not enough, WordDefiner even lets you see words that follow or precede the ones you look up, which nouns they typically modify, and which adjectives often modify them. And if that's still not enough, well, WordDefiner now provides hypernyms, hyponyms, holonyms, and meronyms!

When it comes to looks, the dark, minimalistic design isn't all that's easy on the eyes: WordDefiner lacks unnecessary account creation, distracting banner ads, and bloated trackers. Learn new words and study old ones ad and worry-free with the WordDefiner English Dictionary!

There's more to love: WordDefiner is an open-source app, meaning that its codebase is freely available on GitHub. If interested, this enables you to:
1) Ensure that no nefarious background activity is conducted by this app;
2) See/learn the inner workings of this app; and,
3) Customize builds per your liking for any device.
