人英语要怎么说呢

"人" means "person" in English. You can say "a person" or just "a person" to refer to an individual human being. For example, you could say "There is a person at the door" or "I saw a person walking down the street."
It's also worth noting that "人" is a common character in Chinese, Japanese, and Korean, and it is often used to refer to people in these languages as well. In Chinese, for example, you could say "一个人" (yī gè rén) to refer to a person, or "人类" (rén lèi) to refer to humanity or the human race. In Japanese, you could say "ひとり" (hitori) to refer to a person, or "人類" (jinrui) to refer to humanity or the human race. In Korean, you could say "일명" (ilmyeong) to refer to a person, or "인간" (ingan) to refer to humanity or the human race.
