Noun clause-Embedded questions

 Embedded Questions 

1.      The form

We say:       Where has Tom gone?

But     Do you know where Tom has gone? (not Do you know where has Tom gone?)

When the question (Where has Tom gone?) is part of a longer sentence (Do you know …?/ I don’t know …/ Can you tell me …? etc.), the word order changes. We say:

-What time is it?

-Who are those people?

-Where can I find Linda?

-How much will it cost?

à Do you know what time it is?

à I don’t know who those people are.

à Can you tell me where I can find Linda.

à Do you have any idea how much it will cost?

Be careful with do/does/did questions. We say:

-What time does the film begin?

-What do you mean?

-Why did she leave early?

à Do you know what time the film begins?

à Please explain what you mean.

à I wonder why she left early.

Use if or whether where there is no other question word (What, why.) :

Did anybody see you?

à Do you know if anybody saw you?

Or

Do you know whether anybody saw you?
