If you rearrange the sentence, you get "Your teacher is like what". How would you classify "what"?
Student or Learner
As far as I learn, "what" is a noun or a pronoun while "how" is an adverb.
But how can I understand " What is your teacher like?" In this sentence, is “what " a noun or an adverb?
Usually, we will answer this kind of question with an adjective, like "good, tall, etc." not a noun.
