别人用英语应该怎么说

If you want to ask someone in English how to say something in English, you can ask "How do you say [word or phrase] in English?" or "What is the English translation for [word or phrase]?" For example, you might say "How do you say 'hello' in English?" or "What is the English translation for 'Bonjour'?"
It's also important to consider the context in which you are asking for a translation. If you are in a conversation with someone and you want to know how to say something in English, it may be more natural to simply ask "What does [word or phrase] mean in English?" For example, you could say "What does 'Bonjour' mean in English?"
It's always a good idea to be polite and to use appropriate language when asking for help or information, so it's a good idea to begin your question with a greeting such as "Hi" or "Hello."
I hope this helps! Let me know if you have any other questions.
