Learn to read the feeling and meaning of a sentence so you can pick the perfect missing word.
People have been using clues to figure out missing words for a very long time! Think about it — when someone leaves a note and the ink smudges a word, you use the rest of the sentence to guess what it said. That is exactly what sentence completion questions ask you to do on the ISEE.
On the ISEE Lower Level test, you will see about 17 sentence completion questions. Each sentence has one blank and four answer choices (A through D). Your job is to find the one word that makes the sentence complete and makes sense. Let's learn exactly how to do that!
There are two big tools that help you solve sentence completions: tone and logic. When you use them together, you become a word detective!
Let's look at a diagram that shows how tone and logic work together. Imagine you read a sentence and need to figure out what kind of word belongs in the blank. The diagram below shows the two questions you should always ask yourself.
Notice how tone and logic are like two spotlights pointing at the same stage. When both spotlights land on the same answer, you know you've found it!
Signal words are the secret helpers hidden inside sentences. They tell you what direction the blank should go. Let's split them into two teams: Same-Direction words and Opposite-Direction words.
Words like because, so, since, and, and therefore mean the blank continues the same idea. If the sentence sounds positive before the signal word, the blank will also be positive.
Words like but, however, although, even though, and yet mean the sentence is about to flip. If the first part sounds happy, the blank might be a sad or surprising word.
Sentences on the ISEE can have different tones. Some sound happy and upbeat. Others sound serious or worried. Let's look at the main tones you'll see and the kinds of words that go with each one.
| Tone | How It Feels | Words That Fit |
|---|---|---|
| Positive ☀️ | Happy, proud, hopeful, excited | joyful, thrilled, kind, generous, successful |
| Negative 🌧️ | Sad, worried, angry, disappointed | gloomy, frustrated, careless, difficult, lonely |
| Neutral 😐 | Calm, factual, informational | common, ordinary, typical, usual, necessary |
| Surprising 😲 | Unexpected, shocking, amazing | astonishing, remarkable, unusual, rare, incredible |
Here is a simple trick: Before you look at the answer choices, try to guess your own word for the blank. Then see which choice is closest to your guess. This keeps you from being tricked by a word that sounds fancy but doesn't fit!
Let's walk through a real sentence completion together. Follow each step carefully!
Answer choices: (A) worried (B) confused (C) prepared (D) lazy
Great job following along! Notice how we used tone (positive feeling) and logic (signal words) together. That's the winning combo!
Let's compare the smart strategies with the common mistakes students make. Knowing what NOT to do is just as important as knowing what to do!
| Smart Strategy ✅ | Common Mistake ❌ |
|---|---|
| Read the WHOLE sentence before looking at choices. | Reading only the part near the blank and jumping to an answer. |
| Predict your own word first, then match it. | Picking the fanciest or longest word because it "sounds smart." |
| Look for signal words to know the direction. | Ignoring signal words and guessing based on one word in the sentence. |
| Eliminate wrong answers first, then choose. | Picking the first answer that seems okay without checking the others. |
| Always answer every question — no penalty for guessing! | Leaving a question blank because you are unsure. |
Tone and logic are your main tools, but having a strong vocabulary makes you even better at this! The more words you know, the easier it is to find the right answer. Here are some tips for building your word power.
| Skill | What It Means | How It Helps on the ISEE |
|---|---|---|
| Read Every Day | Read books, magazines, or articles for at least 20 minutes daily. | You learn new words naturally by seeing them in sentences. |
| Learn Word Parts | Study prefixes (un-, re-, pre-), suffixes (-ful, -less), and roots. | Even if you don't know a word, you can break it apart and guess its meaning. |
| Use Context Clues | Figure out a new word's meaning from the words around it. | This is exactly what sentence completion questions test! |
| Know Positive vs. Negative | For each new word, learn if it is a "good" word or a "bad" word. | Even a rough guess about tone can help you eliminate two answer choices instantly. |
Remember, you do not need to know every word perfectly. If you can tell whether a word is positive or negative, you can use tone and elimination to get the right answer. You've got this!
Now it's your turn! Use tone and logic to find the best word for each blank. Remember: read the whole sentence, find signal words, check the tone, predict a word, and then pick the closest match. Let's go!
You now have two powerful tools for ISEE sentence completions! First, check the tone — is the sentence positive, negative, neutral, or surprising? The missing word must match that feeling. Second, use logic by finding signal words like "because" (same direction) and "although" (opposite direction). Always predict your own word before looking at the choices, then use process of elimination to cross out answers that don't fit.
Remember: the ISEE has no penalty for wrong answers, so never leave a question blank. Even if you can only eliminate one choice, guess from the remaining ones. Build your vocabulary by reading every day and learning word parts. You are a word detective — use tone and logic as your magnifying glass, and you'll crack every sentence completion on test day!
