There's a word for that?
By many estimates, there are more than 300,000 words in the English language. At least, unabridged dictionaries tend to include this number of entries, depending on how they define a word. (Are both run and running included? Are phrases, like pre-main sequence stars, words?)
While 300,000 is a big number, there’s a vastly larger number of experiences, emotions, and social interactions than that. Which is to say that some things in the human experience simply don’t have an English word to describe it. That’s when knowledge of another language or two (or at least a limited vocabulary from another language) can prove most useful.
These words may not have a direct translation (hence why they’re often called “untranslatable”), but they can be invaluable for getting your point across. The next time you’re at a loss for words, maybe one of these can help you out.
