"How do people say in English?"
This is a straightforward question that can be answered in one word: "English." However, if you're looking for a more nuanced or idiomatic answer, the phrase "in English" could be used to indicate that someone is speaking or writing in the English language. This phrase emphasizes the language itself as opposed to the specific words being spoken or written. So, in short, when someone asks "How do people say in English?", they are really asking about how people communicate in English.
