Direct and indirect questions
A direct question stands alone: "Where is the station?" The verb comes before the subject.
An indirect question is hidden inside a longer sentence. We start with a frame like "Do you know", "Could you tell me" or "I wonder". Then we use statement order: question word + subject + verb.
- Where is the station? → Do you know where the station is?
- What does he want? → I don't know what he wants. (no do/does)
- When did they leave? → Tell me when they left.
There is no question mark after "I wonder where he lives". In "Do you know where he lives?" the whole sentence is still a question, so it keeps the mark.
Yes/no questions with if or whether
A yes/no question has no question word. When we move it inside a sentence we add if or whether.
- Is he home? → I wonder if he is home.
- Does she like tea? → Can you tell me whether she likes tea?
"If" is common in speaking. "Whether" is a little more formal and works well with "or not": "I don't know whether he will come or not."
SVO with a that-clause or wh-clause
SVO means Subject + Verb + Object. Usually the object is a noun: "I like music". But the object can also be a clause, a small sentence with its own subject and verb.
- I think that she is kind. ("that" can be left out)
- He said that he was tired.
- I know what she wants.
- Please tell me how you did it.
Verbs often followed by such a clause: think, know, say, hope, believe, tell, ask, understand, remember.
SVOC: make, call, name, find, keep
SVOC means Subject + Verb + Object + Complement. The complement says what the object is, or what the object becomes. You can test it: Object is Complement.
- We call the cat Tama. (the cat is Tama)
- They named the baby Aarav.
- The news made me happy. (I am happy)
- I found the film boring.
- Please keep the door open.
Compare SVOO: "She gave me a book" (me is not the same as a book). In SVOC the object and complement are about the same thing.
Key formulas and definitions
- Indirect question: frame + wh-word + subject + verb
- Yes/no indirect: frame + if/whether + subject + verb
- SVO clause: S + V + (that) + clause
- SVOC: S + V + O + C (O = C)
- Key terms: clause, object, complement, statement order
Worked examples
1. Change to an indirect question: "Where does Ravi live?" Start with "Do you know".
Do you know where Ravi lives? Remove "does", put the subject first, and the verb gets the -s.
2. Join with "if": "Is the shop open?" / "I wonder".
I wonder if the shop is open.
3. Name the pattern: "The teacher made the class quiet."
SVOC. S = The teacher, V = made, O = the class, C = quiet. The class is quiet.
4. Which is correct? "I don't know what is his name" or "I don't know what his name is"?
"I don't know what his name is." After the wh-word, use statement order: subject (his name) then verb (is).
Common mistakes
- Keeping question order inside the sentence: "Do you know where is the station?" Correct: where the station is.
- Keeping do/does/did: "I wonder what does he want." Correct: what he wants.
- Forgetting if/whether in yes/no questions: "I wonder he is home." Correct: I wonder if he is home.
- Mixing SVOO and SVOC: "She made me a cake" is SVOO. "She made me angry" is SVOC.
