What are some words in your language that have no equivalent in other languages? For English, I would say the word "awkward" is an example; as in, a certain nervous feeling you get when a situation makes you uncomfortable. But it's different from just being nervous, it's more like uncertainty or tension. For example if you confessed to your crush that you like them, but it turns out they are already dating someone, that would make the situation between you two very awkward. I've found that some languages, like Portuguese, have no direct translation for this word.
