# TOEFL Word Order: 20 Embedded-Question Drills | topin

## Find the outer question and the inner clause

ETS’s Build a Sentence task asks you to arrange words or phrases into a grammatical sentence or question. The current specifications list ten items. These exercises practise embedded questions because the same pattern also supports clear requests in the email task. They are grammar drills, not an exact copy of the official interface.

Cambridge’s grammar reference distinguishes ordinary question order from indirect question order. In a direct question, an auxiliary commonly precedes the subject: where does the seminar start? In an embedded clause, use the subject before its verb: could you tell me where the seminar starts? The outer question still has its own question order.

__Original clause comparison based on standard question-order rules.__
| Sentence type           | Example                                   | Clause order                               |
| ----------------------- | ----------------------------------------- | ------------------------------------------ |
| Direct question         | When does the workshop begin?             | Question word + auxiliary + subject + verb |
| Embedded in a question  | Do you know when the workshop begins?     | Outer question; inner subject + verb       |
| Embedded in a statement | I wonder when the workshop begins.        | Statement; inner subject + verb            |
| Yes/no embedded clause  | Could you check whether the room is open? | Whether + subject + verb                   |

For direct subject questions such as who booked the room, there is no extra do solely for inversion. That makes some transformations look unchanged. Identify the role of the question word before adding an auxiliary mechanically.

See the [Build a Sentence overview](/toefl/writing/build-a-sentence) for task mechanics. This page isolates the clause-order skill and uses complete answers so you can inspect why the reconstruction works.

## Use a clause-first reconstruction method

First read the conversation context and identify the function of the reply. Is it asking for information or reporting what somebody asked? Then find the outer frame, such as do you know, could you tell me or she asked. That frame determines the order outside the embedded clause.

Next locate the inner subject and verb. In could you tell me where the files are, the files is the inner subject and are is its verb. Keep them in that order. Do not move are ahead of the subject simply because where signals a question meaning.

If the original direct question contains do, does or did, check whether that auxiliary exists only to form the direct question. In an embedded clause it is normally removed and the main verb carries the relevant form: where does she work becomes where she works. The meaning and time still have to fit the context.

For yes/no information, use if or whether where appropriate. Could you confirm whether the lift is working asks for confirmation; could you confirm is the lift working mistakenly uses a direct question as the inner clause. The drills below use supplied options to keep the expected construction clear.

Finally read the whole answer, checking that both clauses are complete and the intended question has survived. A grammatical sequence that asks where when the speaker needs when is still the wrong reply. This matters in the [email request examples](/articles/toefl-email-request-examples), where the reader must know the actual requested information.

## Drills 1–10: reconstruct the inner clause

Original practice instructions: complete the given outer frame using all the inner-clause chunks. The slash-separated chunks belong inside the frame, not to the full test interface. Read each item once, attempt it before checking the answer, and explain the inner subject and verb.

__Ten original embedded-clause reconstructions; answers are for review after your attempt.__
| Item and frame               | Inner chunks                          | Correct answer                                         |
| ---------------------------- | ------------------------------------- | ------------------------------------------------------ |
| 1\. Do you know …?           | the seminar / where / is              | Do you know where the seminar is?                      |
| 2\. Could you explain …?     | this card / how / works               | Could you explain how this card works?                 |
| 3\. Please tell me … .       | starts / the lecture / when           | Please tell me when the lecture starts.                |
| 4\. I wonder … .             | the office / whether / is open        | I wonder whether the office is open.                   |
| 5\. Can you check …?         | we / should / which entrance / use    | Can you check which entrance we should use?            |
| 6\. Do you remember …?       | the printer / who / repaired          | Do you remember who repaired the printer?              |
| 7\. Could you tell me …?     | costs / how much / the membership     | Could you tell me how much the membership costs?       |
| 8\. I would like to know … . | the workshop / has / how many places  | I would like to know how many places the workshop has. |
| 9\. Please confirm … .       | available / whether / the files / are | Please confirm whether the files are available.        |
| 10\. Can you explain …?      | was cancelled / why / the rehearsal   | Can you explain why the rehearsal was cancelled?       |

Items 1, 4 and 9 place a form of be after the inner subject. Items 2, 3 and 7 keep the appropriate present-tense verb. Item 6 is a subject question, so who repaired is already the subject-and-verb sequence. Item 10 keeps the passive was cancelled together after the rehearsal.

Do not memorise only the displayed answers. Replace seminar with consultation and card with booking system, then build a new question. The rule should survive a new noun and verb rather than depend on recognising the original sentence.

If an item is wrong, write the inner clause as a plain statement first. The seminar is in Room C shows subject then verb. Restore where in the information slot and attach the outer question. This is a learning technique, not a required test-day procedure.

## Drills 11–20: contrast direct and embedded order

Original practice instructions: transform each direct question using the supplied outer frame. Preserve the information requested and use a form that fits the displayed context. These are transformation exercises; the official task may instead supply rearrangeable words and fixed parts.

__Ten original transformations.__
| Item and direct question                | Outer frame              | Correct transformation                                  |
| --------------------------------------- | ------------------------ | ------------------------------------------------------- |
| 11\. Where does Nina study?             | Do you know …?           | Do you know where Nina studies?                         |
| 12\. When do the buses leave?           | Could you tell me …?     | Could you tell me when the buses leave?                 |
| 13\. Why did the door lock?             | I wonder … .             | I wonder why the door locked.                           |
| 14\. Is the application complete?       | Please check … .         | Please check whether the application is complete.       |
| 15\. Can we use the studio?             | Could you confirm …?     | Could you confirm whether we can use the studio?        |
| 16\. What does the notice mean?         | Can you explain …?       | Can you explain what the notice means?                  |
| 17\. Who has the key?                   | Do you know …?           | Do you know who has the key?                            |
| 18\. How long will the repairs take?    | Please tell us … .       | Please tell us how long the repairs will take.          |
| 19\. Where are the archived recordings? | I would like to know … . | I would like to know where the archived recordings are. |
| 20\. How many students joined?          | Could you check …?       | Could you check how many students joined?               |

Items 11 and 16 remove direct-question does and put the third-person ending on the main verb. Item 13 removes did and uses the past form locked. Items 15 and 18 retain the modal after the inner subject. Items 17 and 20 are subject questions, so no new auxiliary is needed.

Check whether the outer frame is itself a question. Please tell us is an instruction, while could you tell us is a question. Punctuation helps readers but does not repair wrong clause order. Keep the sentence structure correct before concentrating on the final mark.

## Match an error to the smallest useful repair

Label the cause: outer inversion, inner inversion, unnecessary do-support, subject-question confusion or agreement. A list of ten incorrect answers is less actionable than recognising that eight contain the same inner inversion.

__Original error diagnosis.__
| Error pattern       | Example to repair                                           | Target habit                                          |
| ------------------- | ----------------------------------------------------------- | ----------------------------------------------------- |
| Inner inversion     | Do you know where is the room?                              | Place inner subject before be                         |
| Unneeded does       | Can you explain how does it works?                          | Remove direct-question support and preserve agreement |
| Lost modal          | Please tell us when the repairs take.                       | Preserve will when the context is future              |
| Wrong question word | Do you know where the lecture starts? when a time is needed | Check the requested information                       |
| Subject confusion   | Do you know who does have the key? in a neutral question    | Identify who as the inner subject                     |

Treat the examples as neutral information questions; emphatic structures can behave differently. Do not turn a drill rule into a claim that a word such as does is forbidden in every embedded sentence. The supplied context and intended meaning determine the appropriate construction.

After repair, create two unseen examples with different subjects. Say them, then write them. If the rule disappears while typing quickly, add a short check for the inner subject and verb to your final review routine. One targeted grammar check is easier to perform than scanning vaguely for all errors.

The [four-week study plan](/articles/toefl-four-week-study-plan) shows how to alternate learning and timed transfer. Do not convert success on these twenty rehearsed items into a predicted official Writing band.

## Transfer the grammar into new timed responses

Use the pattern in a fresh email request only when it fits the goal. Could you confirm whether the reservation is correct gives the reader a specific action. Adding embedded clauses everywhere merely to show complexity can make a simple message cumbersome.

* Try each original item before viewing the answer.
* Identify the inner subject and verb in every correction.
* Create new nouns, verbs and situations for a transfer check.
* Distinguish direct questions, embedded questions and subject questions.
* Keep task meaning visible as well as grammar.
* Use a fresh timed task before deciding the error is resolved.

Take topin’s [free TOEFL mock](/toefl/practice-test), marked on the official scale, to check sentence control in a complete current-format sequence. These drills repair a specific skill; a full section also needs task understanding, appropriate development and performance under the clock.

If the grammar is now stable but the email remains incomplete, stop drilling clause order and address the missing goal. Good preparation changes with the evidence. A successful repair should release time for the next real problem rather than become an endless exercise on familiar sentences.

## FAQs

Are these official Build a Sentence items?

No. They are original embedded-clause and transformation exercises, not exact interface replicas or copied ETS questions.

Why is where the room is correct?

Inside the embedded question, the subject precedes the verb. The outer frame can still use question order, as in could you tell me.

Should I remove every do or does?

No. In these neutral transformations, direct-question support is removed from the inner clause where appropriate. The outer question may still use do, and other contexts can use emphatic forms.

Does who always need inversion?

No. In subject questions such as who has the key, who is the subject and the normal subject-verb order is already present.

Can these drills predict my Writing score?

No. They target one grammar skill. Use fresh timed tasks and the full-section evidence to judge preparation, without assigning an official band from a rehearsed drill set.
