Interrogative conjunction?

I have never heard the term "interrogative conjunction".

I think an interrogative conjunction is the "question word" of the sentence. An interrogative sentence is a question, so the interrogative conjunction is like "What", "where" , "how", and "why". So in the sentence "What are you doing?", "what" is the interrogative conjunction.

Anonymousso the interrogative conjunction is like "What", "where" , "how", and "why"

Those are interrogative, but they're not conjunctions.

Oh, never mind about what I just said. Interrogative conjunctions are interrogative words used as conjunctions in statement sentences. (i.e: He showed me where he found the book.)

Subject + verb + interrogative words + subject + verb + other word. This is the structure of interrogative conjunction. For example - I know where she live ?

Wh-question words can be used as questions or conjunctions. Examples:

Wh-question: Where are you going?

Interrogative conjunction: I asked him where he was going.

Notice that with the interrogative construction, the noun and verb are reversed.

This terminology is useful in explaining to my ESL tutees what is happening to the syntax.

If you have a better way to explain this, I'm all ears.
