(A) Following the verb want, can we use a modal verb in an objective clause which begins with that? (B) Also, can we use the simple future (the modal auxiliary will) in an objective clause with that, when it follows the verb want? For example: (A) I want that she can call me tomorrow. Your mother wants that you should leave Aleppo now. We want that you might help us. I want that you can be happy. (B) I want that you will become a physician. I want that you will call me. 1. Are those sentences above incorrect? If so, why? Observations: --If we drop the that, then the sentences are obviously wrong. I want you will become a physician. --Those objective that phrases could work as subjects with no difficulty. That you should leave Aleppo now ought to be obvious to you, dummy. --The sentences above are not how people talk. But I do not know if they are incorrect. If we change the verb to hope, then most of the sentences make perfect sense. Why the difference? Help. More Examples: I wanted that you would call me. I wanted that you could go on vacation.
