Tongues

Every single language has words no other one has, that's what makes the study of different languages so interesting. As well as when they intercept each other. E.g. many German words infiltrated the modern English language: 'Kindergarten', 'Gesundheit', 'Rucksack', 'Angst', 'Wanderlust', just to name a few. Language is organic, it has a life of its own. Und gut so.
