Why You Might Be Using 'What About You?' Completely Wrong in Daily Conversation
The English language rarely maintains two identical phrases without assigning them different functional duties. While both phrases serve as elliptical questions, relying on the preceding sentence to supply their context, their interrogative pronouns dictate their scope. "How" inherently inquires about condition, degree, process, or sentiment. "What" targets identification, categorization, and discrete items.
Consider a simple workplace greeting on a Monday morning. A colleague says, "I spent the entire weekend recovering from a brutal head cold. How about you?"
If you respond, "Good, what about you?", the gears grind. The phrase "What about you?" asks for specific facts relative to the topic just raised: Do you also have a head cold? What is your status regarding illnesses? Conversely, answering with "How about you?" leaves the door wide open for emotional resonance and general condition. The former narrows the frame. The latter expands it.
Native speakers feel this nuance instinctively, even if they cannot diagram the syntax. When someone asks "How about you?", they invite personal sentiment. When they ask "What about you?", they often seek balance in a structured comparison: "I ordered the black cod. What about you?" Here, "what" works cleanly because the universe of discourse is dinner selection. Using "how" in that narrow moment ("I ordered the black cod. How about you?") borders on unnatural, as if asking how you feel about their fish rather than what you intend to eat.
