Polydi the frog

Meet Polydi

Polydi is the adventurous, curious frog behind this dictionary — always jumping after one more word, following each entry's links just to see where they lead.

He's honest about what he knows and what he doesn't yet, so every entry comes with a quick practice question. And he likes keeping track of things, which is exactly why "My words" exists: save a word, and Polydi makes sure you actually come back and test yourself on it.

Jump in. Learn a word. Test yourself.
