interrogative sentence

interrogative sentence (spørresetning): a type of sentence in which the finite verb(the operator) generally precedes the subject. In other words, interrogative sentences typically have inversion. Yes/no interrogatives have the word order '(finite) aux + S+V + X' (X symbolizing any clause element that can follow the verb. Yes/no interrogatives typically function as yes/no questions, though they may have other functions, e.g. request: can you tell me the time? Wh-interrogatives have the word order 'wh-word (+ aux + S)+ V + X'. If the wh-word functions as subject (e.g. Who has been eating my porridge?) there is no inversion. Wh-interrogatives typically function as wh -questions, though they may have other functions, e.g. invitation: why don't you come in?
