They are called "borrowed" - but, of course, they will stay with the language that borrowed them. English has taken many words from many languages - and sometimes their origin is obvious, sometimes it is
quite a surprise. Bolshevik is quite discernibly from Russian, cliché apparently from French, but would you have guessed that jerky is originally from the South American language Quechua?
This book wants to invite you to browse through a list of languages and see which words they have contributed to English. Just read from Afrikaans to Yiddish, and discover which words each of them has contributed. Travel around the world, without ever leaving the English language, and have fun!
