The word like in English has two main forms, as a verb, and as a preposition. Low level learners often confuse the two meanings.
- What is he like?
- What does he look like?
NB: Students will often confuse the different forms of using be v. auxiliary do
NB: Students will often try to use "like" (prep) in their answers to these questions, e.g. *"He is like friendly".
