Why Build a Sentence Deserves Serious Practice
Build a Sentence is the first task you meet in the new TOEFL iBT Writing section, and many students treat it as a warm-up. That is a mistake. Each item is quick, but there are several of them, and every wrong order is a lost point that you cannot recover with a brilliant email later. The good news is that this task rewards a small set of grammar rules applied consistently. Once you understand how English builds statements, direct questions and indirect (embedded) questions, most items become predictable.
In this guide we break down exactly what the task asks, give you a reliable verb-first method, compare question and indirect question word order in a table, list the traps that catch even advanced learners, and walk through five worked examples with full solutions.
What the Task Looks Like
In Build a Sentence you see a short conversational context, usually one person’s line, followed by an incomplete reply. Below the reply is a set of word tiles (single words or short chunks). Your job is to drag the tiles into the only order that produces a grammatical, natural sentence that fits the context. Sometimes one or two words are already fixed in place, and occasionally there is a tile you should think about carefully because it changes the structure.
Timing and scoring at a glance
The whole Writing section runs for roughly 23 minutes and contains Build a Sentence, Write an Email and Write for an Academic Discussion. Build a Sentence items are short, so you should aim to spend well under a minute on each. Items are scored as correct or incorrect: the entire sentence must be in the right order. There is no partial credit for getting most of the tiles right, which is why careful checking matters. Your Writing result is reported on the new 1–6 band scale (with a comparable 0–120 total during the transition period), so always check ETS for the latest official details.
| Feature | What to expect |
|---|---|
| Context | A short spoken-style line from a classmate, colleague or friend |
| Tiles | Roughly 5–8 words or chunks to arrange |
| Common structures | Direct questions, indirect questions, negatives, relative clauses, passives |
| Target pace | About 30–45 seconds per item |
| Scoring | Whole sentence correct or incorrect |
The Verb-First Method: A Step-by-Step Strategy
Most students start by placing the first word they recognise, then get stuck halfway. A faster approach is to find the engine of the sentence first: the verb phrase. Everything else attaches to it.
- Read the context line. Decide what the reply is doing: asking, answering, apologising, suggesting or reporting. This tells you whether you need a question or a statement.
- Find the main verb and any auxiliaries. Look for tiles such as do, does, did, have, has, will, can, could, is, was and the main verb. Pair them up correctly (for example, did … go, has … finished).
- Find the subject. Who or what performs the action? Place it in the right position relative to the auxiliary: before it for statements and indirect questions, after it for direct questions.
- Attach objects and complements. Objects usually follow the main verb directly. Do not split a verb from its object with an adverb.
- Add the extras last. Time phrases, place phrases and adverbs go into their natural slots, normally at the end or just before the main verb.
- Read the whole sentence silently. Check punctuation: does the sentence end with a question mark or a full stop? That is a strong clue to the structure.
Pro Tip: Look at the final punctuation before you touch any tile. A full stop after a phrase like “Could you tell me…” or “I wonder…” almost always signals an indirect question, which uses statement word order.
Question vs Indirect Question Word Order
The single most tested structure in this task is the difference between a direct question and an indirect question. In a direct question, the auxiliary comes before the subject. In an indirect question, which sits inside a larger sentence, the word order returns to normal statement order and the auxiliary do/does/did disappears.
| Type | Pattern | Example |
|---|---|---|
| Direct wh-question | Wh-word + auxiliary + subject + verb | Where did you park the car? |
| Indirect wh-question | Intro phrase + wh-word + subject + verb | Do you know where you parked the car? |
| Direct yes/no question | Auxiliary + subject + verb | Is the library open on Sunday? |
| Indirect yes/no question | Intro phrase + if/whether + subject + verb | I’d like to know whether the library is open on Sunday. |
| Direct question with be | Wh-word + be + subject | What time is the meeting? |
| Indirect question with be | Intro phrase + wh-word + subject + be | Can you tell me what time the meeting is? |
Notice that the intro phrase itself may be a question (Do you know…? Can you tell me…?), so the sentence still ends with a question mark. But the embedded part after the wh-word always uses statement order. This is where most errors happen.
Common Traps That Cost Points
Trap 1: Do-support in the wrong place
In direct questions and negatives with simple present or past verbs, English needs do/does/did. When a tile set includes did, remember the main verb must be in the base form: did she send, never did she sent. And if the sentence is an indirect question, there should be no did at all in the embedded clause. If you see a did tile, it probably belongs to the intro question or the sentence is direct.
Trap 2: Embedded questions with inverted order
Students who speak languages where questions keep the same order everywhere often produce Could you tell me where is the lab? The correct version is Could you tell me where the lab is? When the tiles give you both a wh-word and a form of be, put the subject between them in indirect questions.
Trap 3: Adverb placement
Frequency adverbs (always, usually, often, never) go before the main verb but after be and after the first auxiliary: She has never missed a class; He is usually late. Manner and time adverbs normally go at the end: finished the report quickly yesterday. Never put an adverb between a verb and its direct object (read carefully the instructions is wrong).
Trap 4: Prepositions and phrasal verbs
Chunks such as looking forward to, in charge of or depend on must stay together. In questions, the preposition often moves to the end: Who are you waiting for?
Trap 5: The distractor feeling
If a sentence seems to need a word that is not there, re-check your structure. Usually you have chosen a direct question where an indirect one is needed, or vice versa.
Five Worked Examples with Solutions
Example 1: Indirect wh-question
Context: “I’m new on campus and I’m a bit lost.”
Tiles: could / tell / the / you / me / bookshop / where / is
Solution: Could you tell me where the bookshop is?
Why: The intro Could you tell me is a polite direct question (auxiliary could before you). After where, the embedded clause uses statement order: subject the bookshop + verb is.
Example 2: Direct question with do-support
Context: “I finally submitted my scholarship application.”
Tiles: did / when / hear / you / back / expect / to
Solution: When did you expect to hear back?
Why: Wh-word, then auxiliary did, then subject you, then base verb expect. The infinitive to hear back stays together as the complement.
Example 3: Indirect yes/no question
Context: “The professor said the deadline might change.”
Tiles: I / whether / wonder / been / has / it / extended
Solution: I wonder whether it has been extended.
Why: I wonder is a statement, so the sentence ends with a full stop. Whether introduces the embedded yes/no question, followed by statement order with a present perfect passive: it has been extended.
Example 4: Adverb placement in a negative
Context: “Why didn’t Priya join the study group?”
Tiles: she / usually / doesn’t / on / weekends / study / with others
Solution: She usually doesn’t study with others on weekends.
Why: The frequency adverb goes before the auxiliary in this negative pattern, the base verb follows doesn’t, and the time phrase goes at the end. (She doesn’t usually study… would also be natural, but the tiles and the fixed slots in the test will only allow one arrangement, so match what is available.)
Example 5: Relative clause
Context: “Which article should I read first?”
Tiles: the one / start with / that / I’d / recommended / the tutor
Solution: I’d start with the one that the tutor recommended.
Why: Main clause first (I’d start with + object the one), then the relative clause that the tutor recommended in statement order to describe it.
Common Mistakes Checklist
- Inverting the subject and verb inside an indirect question.
- Keeping did and also using a past-tense main verb (did you went).
- Ignoring the final punctuation mark, which reveals the structure.
- Splitting fixed chunks such as phrasal verbs or infinitives.
- Placing adverbs between the verb and its object.
- Spending two minutes on one item and rushing the email as a result.
- Submitting without reading the full sentence once from start to finish.
A Practice Routine That Builds Automatic Accuracy
Word order improves through short, frequent practice rather than occasional long sessions. Try this two-week routine.
| Day | Focus | Drill |
|---|---|---|
| 1–2 | Direct questions | Turn 20 statements into wh- and yes/no questions |
| 3–4 | Indirect questions | Rewrite 20 direct questions starting with “Do you know…” or “I wonder…” |
| 5–6 | Adverbs and negatives | Insert frequency adverbs into 15 sentences with different auxiliaries |
| 7 | Mixed timed set | 15 tile items at 40 seconds each; log every error |
| 8–13 | Weak areas | Repeat the drill type you missed most, then a mixed set |
| 14 | Full Writing section | Sit a timed mock and review your mistake log |
The mistake log is the key. Write down the wrong order you chose, the correct order and the rule you broke. After a week you will see that your errors cluster around one or two patterns, and fixing those patterns is far more efficient than doing hundreds of random items. This is exactly how TOEFL Prep Guide’s mistake reports work: every wrong item is tagged by rule so you know what to drill next.
Pro Tip: Say your answer under your breath before submitting. Your ear often catches inverted indirect questions and misplaced adverbs faster than your eyes do.
Conclusion: Small Task, Big Payoff
Build a Sentence is the most learnable part of the Writing section. Master the verb-first method, respect the difference between direct and indirect question order, and keep a careful eye on adverbs and do-support, and you can turn these items into reliable points while saving time for the email and academic discussion.
