How do you answer 'how art thou?

Answer 1

"Fine, I thank thee", or possibly "Lousy, I thank thee not", or even "None of thy damn business."

In any case "How art thou"="How are you" and can be answered accordingly.

Answer 2

Oh, dude, you're hitting me with some Shakespeare vibes there. So, "how art thou" is basically like asking "how are you" in old-timey speak. You could reply with something like, "I'm good, thanks for asking," or if you want to keep it real old-school, you could say, "I am well, kind sir/madam." But like, no pressure, it's not like we're performing a play or anything.

Answer 3

The phrase "how art thou" is an archaic way of asking "how are you" in Early Modern English. The response to this question would typically be something like "I am well" or "I am doing fine." In modern English, the equivalent question would be "how are you" or "how are you doing."
