The Global Language Monitor estimates that there are currently 1,009,753 words in the English language. Despite this large lexicon, many nuances of human experience still leave us tongue-tied. And that’s why sometimes it’s necessary to turn to other languages to find le mot juste. Here are fifteen foreign words with no direct English equivalent.
