Master sentence completions by reading for clues in every sentence's tone and meaning.
Standardized tests have used sentence completion questions for more than a hundred years. The idea is simple: a sentence with a missing word tells us a lot about how well you understand language. Test-makers realized early on that this question type measures both vocabulary knowledge and reading comprehension at the same time.
The ISEE, which stands for Independent School Entrance Examination, was first given in the 1960s. Its Verbal Reasoning section has always included sentence completions. These questions don't just test whether you know big words. They test whether you can figure out what a sentence needs based on its overall meaning and feeling.
Here's the key question this lesson answers: how do you quickly and confidently pick the one word (out of four) that fits both the meaning and the tone of a sentence? Let's find out.
Every sentence completion question on the ISEE gives you a sentence with one blank. Your job is to find the word that completes the sentence so it makes perfect sense. To do this well, you need to understand three big ideas.
The diagram below shows the decision-making process you should follow every time you see a sentence completion question. Think of it as your step-by-step roadmap. Start at the top and work your way down.
Notice how the flowchart splits at Step 2. If you spot a same-direction signal word like "because" or "therefore," the blank should agree with the rest of the sentence. If you find an opposite-direction signal word like "although" or "however," the blank should contrast with the rest of the sentence. This one step alone can help you eliminate two or three wrong answers instantly.
Meaning and tone are like two teammates that always work together. Meaning tells you what the sentence is talking about—its subject, facts, and logic. Tone tells you how the speaker or writer feels about it. A wrong answer on the ISEE often gets one of these right but not the other.
| Tone Type | What It Feels Like | Example Words |
|---|---|---|
| Positive (+) | Happy, approving, admiring, hopeful | praised, talented, generous, thriving |
| Negative (−) | Sad, critical, worried, disapproving | blamed, careless, harmful, declining |
| Neutral (0) | Factual, balanced, informational | observed, reported, typical, standard |
Signal words act like road signs. They tell you which direction the sentence is heading. Here is how they break down:
| Signal Type | Common Words | What They Do |
|---|---|---|
| Same-Direction | because, since, therefore, so, and, in addition, for example | The blank agrees with or continues the rest of the sentence. |
| Opposite-Direction | although, however, despite, but, yet, instead, rather than | The blank contrasts with or reverses the rest of the sentence. |
| Cause-and-Effect | as a result, consequently, due to, led to | The blank is either the cause or the result of what the sentence describes. |
Let's see how signal words work inside real sentences. The diagram below shows two example sentences side by side. One uses a same-direction signal word, and the other uses an opposite-direction signal word. Notice how the correct answer changes completely.
Look at the top two boxes in the diagram. The sentences are almost identical, but the signal word changes everything. With "therefore" (same direction), the blank should match "careful and precise"—so "accurate" fits. With "however" (opposite direction), the blank should contrast with "careful and precise"—so "flawed" fits. This is why finding the signal word is step number two in our strategy.
The bottom part of the diagram shows the connotation check. Connotation means the feeling a word carries beyond its dictionary definition. "Thrifty" and "stingy" both mean someone doesn't spend much money, but "thrifty" sounds positive and "stingy" sounds negative. On the ISEE, paying attention to connotation is often the difference between getting a question right and falling for a trap.
Let's walk through a full sentence completion question using every step from our strategy flowchart.
(A) boring (B) entertaining (C) lengthy (D) expensive
The ISEE puts wrong answers in there for a reason. They're designed to look tempting! Here are the most common traps students fall into, and how to dodge them.
| Trap Type | What Happens | How to Avoid It |
|---|---|---|
| Right Topic, Wrong Tone | An answer choice relates to the subject but has the wrong positive/negative feeling. Example: "boring" when you need something positive about a movie. | Always do the connotation check. Ask: is this word positive, negative, or neutral? Does it match what the sentence needs? |
| Ignoring the Signal Word | A student misses "although" or "however" and picks an answer that goes the same direction instead of the opposite. | Circle or underline signal words before looking at the answer choices. Make it a habit! |
| Off-Topic Distractor | A word sounds fancy or impressive, but it doesn't relate to the sentence's meaning at all. Example: "expensive" when the sentence is about enjoying a movie. | Re-read the sentence with your chosen word plugged in. Does the sentence make complete, logical sense? |
| Close Synonym Trap | Two answer choices seem very similar, but one has a slightly different connotation. Example: "thrifty" (positive) vs. "stingy" (negative). | When two choices look alike, focus on the tone difference. The one that matches the sentence's feeling is the winner. |
Sentence completions aren't just test questions—they build skills you'll use in reading comprehension, essay writing, and even the Upper Level ISEE. Here's how the skills compare.
| Skill | Middle Level (Now) | Upper Level (Later) |
|---|---|---|
| Signal Words | Spot basic signals like "although," "because," and "however." | Recognize subtler signals like "notwithstanding," "paradoxically," and implied contrasts with no signal word. |
| Vocabulary | Words at the grade 6–7 level; context clues help even if you don't know the word. | More challenging vocabulary; connotation differences are subtler and harder to detect. |
| Tone Analysis | Classify tone as positive, negative, or neutral. | Distinguish between shades of tone: "skeptical" vs. "hostile," "enthusiastic" vs. "cautiously optimistic." |
| Prediction | Predict a simple word or phrase ("something good") before looking at choices. | Predict a precise word that captures both meaning and degree ("not just good—exceptionally innovative"). |
The great news is that every sentence completion you practice now builds your vocabulary and your ability to read between the lines. These same skills will help you on the Reading Comprehension section of the ISEE, in your English classes, and even in everyday conversations. When you start noticing signal words and tone in books, articles, and even text messages, you'll know you're becoming a stronger reader!
Try these five sentence completion problems. Use the five-step strategy for each one: read the sentence, find the signal word, determine the tone, eliminate wrong choices, and pick the best fit. The problems get harder as you go.
On ISEE Middle Level sentence completions, you need to find the one word that matches both the meaning and the tone of the sentence. Start by reading the whole sentence, then hunt for signal words like "although," "however," "because," and "therefore." These words tell you whether the blank goes in the same direction as the rest of the sentence or in the opposite direction.
Next, use the connotation check to classify each answer choice as positive, negative, or neutral. Predict your own word before looking at the choices, then use process of elimination to cross off answers that don't fit. Remember: there's no penalty for guessing on the ISEE, so always answer every question. With practice, these steps will become second nature!
