What is this?

A flashcard trainer for cognates — words that share a common ancestor across languages. Romance languages (Spanish, French, Italian, Portuguese) and English share thousands of cognates from Latin, and a handful of predictable sound changes (p → b, ct → ch / tt / it, e → ie) let you guess vocabulary in a new language with surprising accuracy.

The word lists here are pulled from the Romance Cognate Explorer, so every entry is a real cognate with a documented sound-change history. The trainer is intentionally simple: flip the card, decide if you'd have got it cold, move on.
