Embedded Questions and Content Questions
WHO WHAT WHEN WHERE HOW WHY
These are typical Content Question words which begin a question-sentence in English and they are GREAT for evoking extended conversations and quality answers.
Question formation typically inverts or changes the order of the VERB and the SUBJECT
WHEN DID THE TEACHER GIVE US THE HOMEWORK?
Here THE TEACHER is the SUBJECT and it is AFTER the AUXILIARY VERB = DID. This indicates that it is indeed a question
However we can use each of these SIX CONTENT QUESTION MARKERS to form ADVERBIAL CLAUSES which are dependent clauses connected to the main or INDEPENDENT CLAUSE of a COMPLEX SENTENCE.
This is a simple sentence, but I can then add more information as to WHERE I want to go like:
I WANT TO GO WHERE YOU’RE GOING.
Here we have a Complex Sentence with two clauses and verb phrases. Notice that it’s NOT A QUESTION: Even though we are using WHERE, the SUBJECT/VERB order is not inverted and there’s no [?] Question Mark at the end.
This is called an EMBEDDED QUESTION
I WANT TO DO WHAT YOU ARE DOING.
HE DOESN’T KNOW WHO YOU KNOW.
WE’LL GO WHEN THE LAST TRAIN COMES.
THEY’LL TELL ME HOW TO DO IT.
I WONDER WHY SHE’S NOT HERE YET.
All of these are complex and Embedded Questions, which means that they are not questions at all.
