This is brilliant. I'm lost for words (bad joke sorry but I couldn't resist!). But seriously, you've done an amazing job with this app. The tree structure explanations and level of content in 'detail' is fantastic. Well done and thank you!

Best Etymology App
As a logophile I adore this app. Thanks for providing such a useful app for free. I use it to learn new words as knowing the roots of the words helps me learn them better.
This app is very useful for me and informative, however the text is sometimes difficult to read because of a lack of contrast between the print and the background.

Finally, a quick and easy way to see a word's origins. Clean and clear and fast.
Great app!! I was looking for such kind of app which provides trees of words. Before, I used to view words on google dictionary. But this is definitely best and easy to use app!!

Explore the Etymology Tree

Scroll through thousands of years of language development. Start at a new word, or one you want to explore deeper, then move backwards in time through Latin roots, Ancient Greek words, and Proto-Indo-European reconstructions from 10,000 years ago!

Over 1,400,000 words to explore

With over 1.4M words to explore, you’ll always find that words you’re wondering about, and you’ll never run out of new words to learn. In the English language alone, the app houses 300k words. The rest are spread throughout other languages. 

Full detail page

The connections aren’t the only thing interesting. Check out the full details of the word including the part-of-speech, the full written etymology, the pronunciation, definitions for each part of speech, and any descendant words. 

Family Explorer

No word is an island, and the Family Explorer helps you uncover the hidden, and sometimes shocking, bridges between cognates. For example, ‘voracious’ is a cousin to ‘carnivore’! Check out millions of relations just like that in the app. 

Children Explorer

Words may start with a single meaning, but they expand and morph over time because of the need to explain our increasingly complex world. The Children Explorer shows how root words can give birth to thousands of different meanings in modern language. For instance, Latin ‘gravis’ (“heavy”) is the root of ideas like ‘gravity’, ‘gravid’ (pregnant), and ‘grave’ (serious).

Audio & Newspaper Pronunciations

When I started looking up words, the IPA (e.g. “/mæɡˈnæn.ɪ.məs/”) was nearly indecipherable. So I’ve implemented audio and newspaper pronunciations for the majority of words. Now you can understand how to pronounce a word by hearing it, or by reading normal letters, none of the IPA jumble.


Studying for graduate exams nearly crushed me. I couldn’t memorize any vocabulary… until I discovered etymologies.

Learning a word through its connections fits with how my brain works. I grew more and more excited to interpret a word through its roots and cognates (basically a word “cousin”).

But I wanted more than just a sentence describing where a word came from. I wanted a map that traced back through all the known languages of civilization—and then forward to the full array of descendants. One that I could hop around on from node to node and connection to connection.

It didn’t exist—so I created it. That ended up taking many years and a lot of technology (natural language processing, deep learning, cloud computing). I’ve condensed everything down into this app, EtymologyExplorer. I hope you enjoy using it as much as I have.
