Look at these two examples:
Why did Dolores try to flood the forge?
Why Dolores tried to flood the forge?
Is the second example grammatically wrong as the helping verb is not used before the subject in the interrogative sentence? What is the exact rule for constructing this type of interrogative sentences?
Best Answer
There is one subject and two verbs! If you want to form an interrogative sentence, a question, you must have a helping verb or an auxiliary one. That said, the first sentence is correct
The second sentence may not be considered as interrogative because it does not have the helping verb though it has another verb try.
However, the second sentence can be used in certain context provided it should not be called a question or interrogative sentence. Rather, it would be a normal sentence.
