Which of the following is correct?
"What do you think about?"
"What you think about?"
For formal communication, you need a verb: “What do you think about autumn?” or, “What are you thinking about now?”
In informal communication, you can get by without it, but the wording would have a very slangy (if not uneducated) feel:
What you think about the new uniforms?
Love ’em – they are epic!
Incidentally, when spoken, the first line of that dialog would probably sound something like this: “Whatchu think about the new uniforms?”
