English Declarative and Interrogative Sentences
As stated above, declarative sentences simply make statements. But a declarative sentence can be easily turned into an interrogative sentence that asks a question; simply add an auxiliary verb such as do, did, or will, rearrange the word order, and sometimes change the form of the verb. For example:
Mary is going to the store. (Is Mary going to the store?)
Mary went to the store. (Did Mary go to the store?)
Mary will go to the store. (Will Mary go to the store?)
Of course, it is grammatically correct to add a question mark to the end of every question.
Sometimes it is possible to use inversion to create a question from a declarative sentence. Inversion involves switching the verb and subject around. For example,
Mary is at the store. (Is Mary at the store?)
English declarative sentences can also be turned into questions by adding a few words to the end of the sentence. For example:
Mary went to the store. (Mary went to the store, didn’t she?)
Mary didn’t go to the store. (Mary didn’t go to the store, did she?)
As illustrated above, there are three main methods for turning declarative sentences into questions. The methods for creating interrogative sentences in Latin are less complicated.
