I have two sentences. I would like to know which one is correct. Please help me to understand.

"Is the apartment is still available to rent?"
"Does the apartment is still available to rent?"

    Can you tell us where you got these sentences? Is this an exercise from a book, or are these sentences you are writing? That information can be very helpful; you can read more here.

    @RJay Neither is correct. Can you tell us why you want to use the verb to be twice in the first sentence? This is the kind of detail we need... Sep 15, 2016 at 20:39

You cannot use "do" as a question word with "is". "Do" means to act. The word "do" is used in questions to ask whether the action is being performed or not. While "is" is a verb, it does not describe an action.

To form a question with "is", start with the statement:

The apartment is still available to rent.

Now instead of adding "does" as a question word, move "is" to the beginning:

Is the apartment still available to rent?

    What "do" means is irrelevant. There is a small class of verbs which form questions and negatives without "do": modals such as "can", "may", "will", "ought"; All parts of "be"; and some uses of "have" (for some speakers, all uses of "have"). All other verbs require "do" to form their negative and interrogative.

Is the apartment still available to rent? / Is the apartment available to rent still? (Both are correct) but it is incorrect "Does the apartment is still available to rent? "

    Can you edit to give a little more detail about why one is incorrect and the difference between the other two?
