先生英语怎么说

"How to say '先生' in English?"

In English, "先生" is translated as "Mr." or "Mister." This title is commonly used as a form of respect for a man, typically one in a position of authority or older age. It is important to note that using "Mr." with a person's surname can be considered more formal than using just "Mister." For example, you would write "Mr. Smith" instead of "Smith." However, if you do not know the person's surname, "Mister" is a more common and neutral way to address someone without assuming their gender.
