Cognates

Cognates are words in different languages that share an ancestor. English mother, German Mutter, Latin māter, Greek mētēr, Sanskrit mātṛ́ all trace back to the same Proto-Indo-European word. This browser lets you look them up two ways: search by concept (pick a word, see every language that has it), or by language pair (what did English borrow from Latin?).
