TOEFL Complete the Words: How to Master This 2026 Task Type
"Complete the Words" is the first task you'll see in the TOEFL Reading section under the January 2026 format — and it's easy to underestimate. It looks like a simple fill-in-the-blank exercise: a short academic paragraph with about ten words missing some of their letters. But this task does something none of the others do: your accuracy here helps decide how hard your next passage will be.
This guide breaks down exactly how the task works, a step-by-step method for solving it under time pressure, and a fully worked example — taken directly from TOEFL Practice Test 8 on the Zistre platform — with the reasoning behind every answer.

What Is the "Complete the Words" Task?
You're shown one short academic paragraph — three to five sentences on a topic like biology, history, or in this case atmospheric science. Scattered through it are roughly ten words with some of their letters replaced by blanks. Enough letters are left in each word that it's inferable from context and spelling patterns — this isn't a guessing game, it's a word-recognition task.
You get about six minutes for the full paragraph, which works out to roughly 30–35 seconds per blank. It's always the very first task in the Reading section, before "Read in Daily Life" or "Read an Academic Passage."
Where It Fits in the Reading Section
The full Reading section runs about 50 items in roughly 30 minutes of base testing time, split across three task types:
| Task | Items | Time |
|---|---|---|
| Complete the Words | ~10 blanks | ~6 min |
| Read in Daily Life | ~13 questions | ~8 min |
| Read an Academic Passage | ~27 questions | ~16 min |
Here's the part most test-takers miss: the Reading section is adaptive, and Complete the Words is its router. How you perform on this first task helps determine the difficulty of the Read an Academic Passage module you see later. It isn't a low-stakes warm-up you can rush through — treat every blank with the same care you'd give a scored multiple-choice question.
Step-by-Step Strategy to Solve It Fast
- Read the whole paragraph once before filling anything in. You need the topic and the flow of the argument before individual blanks make sense.
- Use the given letters as an anchor. Every blank starts with one or more real letters — treat that fragment as the first few letters of the word and think of what completes it.
- Count the blanks. Each missing letter gets its own blank, so the number of blanks tells you the exact letter count. This alone eliminates most wrong guesses.
- Check grammar before you commit. Part of speech, verb tense, and singular/plural all have to match the surrounding sentence — a word that "sounds right" but breaks tense is wrong.
- Look for collocations. Academic English travels in set pairs ("high pressure," "clear skies," "weather patterns"). If a nearby word suggests a common phrase, test that phrase first.
- Reread the finished sentence. Once a blank is filled, read the full sentence back — if it sounds natural, you're almost certainly right.
- Budget ~30 seconds per blank. If you're stuck past that, commit to your best letter-count-matching guess and move on — an educated guess beats an empty blank every time.

Worked Example: A Real Question from Practice Test 8
Here's an actual "Complete the Words" question — item PT8-RS-M1-FM-11 — from TOEFL Practice Test 8 on the Zistre platform, shown exactly as it appears on the desktop test screen:
The paragraph explains how atmospheric pressure shapes weather patterns. Working through it blank by blank:
| Given | Answer | Why |
|---|---|---|
| gene___ | general | “In ___, high pressure…” needs the set phrase “in general”; 3 blanks = “ral” |
| pres____ | pressure | Pairs with “high” as a fixed collocation; 4 blanks = “sure” |
| sk___ | skies | “Clear skies” is the standard weather collocation; 3 blanks = “ies” |
| ca__ | calm | Parallel with “clear”, describing conditions; 2 blanks = “lm” |
| How____ | However | Sentence pivots from good weather to bad — needs a contrast transition; 4 blanks = “ever” |
| l__ | low | Contrasts with “high pressure” earlier in the paragraph; 2 blanks = “ow” |
| sys____ | systems | “Low pressure systems” is the standard term; 4 blanks = “tems” |
| le__ | lead | “Often ___ to” is a fixed verb + preposition pattern; 2 blanks = “ad” |
| wea____ | weather | “Cloudy weather” completes the parallel with “clear skies”; 4 blanks = “ther” |
| precip_______ | precipitation | Follows “cloudy weather and…” — the next logical weather noun; 7 blanks = “itation” |
Notice how almost none of these answers required advanced vocabulary — they required reading the grammar and logic of the sentence, then using the letter count to confirm.
Common Mistakes That Cost Points
- Ignoring the letter count. A word that fits the meaning but not the number of blanks is wrong — always cross-check the count before committing.
- Skipping grammar agreement. A word that reads fine in isolation but breaks tense or number with the rest of the sentence will be marked wrong.
- Overthinking 1–2 letter blanks. These are almost always small connector words (“to,” “a,” “is,” “ow,” “lm” endings) — don't burn 30 seconds on them.
- Treating it as “free points.” Because each blank feels small, it's tempting to rush. Given its role in routing your next passage's difficulty, rushing here is the costliest mistake on the whole test.
- Not rereading the finished sentence. A 5-second reread at the end catches errors a first pass misses.
How to Practice This Task Type
Because this task tests vocabulary at the word-formation level — prefixes, suffixes, and common academic word families — building that vocabulary directly transfers. Our TOEFL Academic Word List guide is a good place to start.
Beyond vocabulary, exposure matters: ETS varies the blank patterns (single-letter gaps, whole-suffix gaps, mid-word gaps), and the fastest way to get comfortable with all of them is to work through real questions under real timing rather than untimed flashcards. That's exactly what the full Reading section overview and our practice tests are built around.

How It Compares to the Old TOEFL
Complete the Words didn't exist before the January 2026 redesign. The previous TOEFL iBT Reading section used only longer, uniformly-difficulty passages with multiple-choice questions — comprehension at the paragraph level, not the word level.
That makes this task a genuine blind spot in most existing TOEFL prep material: books and courses written for the pre-2026 test simply don't cover it, because it's brand new. If your prep materials don't mention “Complete the Words” by name, they're out of date for the current exam.
