Hi
Would you be so kind and tell me the correct answer to the following sentence?
Be quiet! I can`t think clear / clearly if you are talking.
In my opinion, the verb think can be followed by an adverb, i.e. clearly. If I think of the verbal expression think clear, then the answer should be think clear and not think clearly. I am a little bit confused. What`s your opinion on that? What is the correct answer?
Thank you very much.
