Cambridge dictionary says that we don't use 'want' with a that-clause :
I want you to tidy your room before the visitors come. (Not : I want that you tidy your room ...)
An website (https://www.englishgrammar.org/thatclauses/ ) also says : Not all verbs can be followed by that-clauses :
I want you to be happy. (NOT I want that you be happy.)
She wants that she should be respected. This sentence has been taken from Lucent's General English by A. K. Thakur. I think this sentence should be written as : "She wants to be respected".
Is the sentence (from Lucent's General English) grammatically correct or not? Why doesn't 'that-clause' come after 'want'?
