Determine the meaning of a phrase or sentence in context

People have been figuring out unknown words from context (the surrounding words and sentences) for thousands of years. Long before dictionaries existed, readers and listeners had to rely on clues in a conversation or text to understand new or confusing language. This skill is one of the oldest reading strategies in the world.

Here is the big question this lesson answers: How do you figure out what a phrase or sentence really means when you can't just look it up? The answer lies in the clues the author gives you in the text itself.

When you come across a confusing phrase or sentence, the words around it act like a flashlight in a dark room. They shine light on the meaning. There are a few key ideas that will help you every time.

The diagram below shows how a confusing phrase sits in the middle of a passage, surrounded by helpful clues. Notice how clues can appear before and after the phrase you are trying to understand.

As you can see, you are never truly stuck when you encounter a confusing phrase. There are always clues hiding in the text. Your job is to find them, think about what they tell you, and piece together the meaning like a puzzle.

There are four main types of context clues that authors use. Learning to spot each type will make you a stronger reader. Let's break them down one at a time.

Type 1: Definition / Restatement Clues

Sometimes the author directly tells you what a word or phrase means. Look for signal words like "which means," "in other words," "that is," or commas and dashes that set off a definition. For example: "The explorer felt apprehensive—nervous and worried—about crossing the river." The dashes tell you exactly what "apprehensive" means.

Type 2: Example Clues

The author gives specific examples that help you understand the phrase. Watch for words like "such as," "for instance," "like," and "including." For example: "She collected many mementos, such as postcards, ticket stubs, and photographs." The examples show that "mementos" are small items kept as memories.

Type 3: Contrast / Antonym Clues

The author shows the opposite meaning, which helps you figure out the phrase. Signal words include "but," "however," "unlike," "although," and "instead." For example: "Unlike her timid brother, Maria was audacious and always the first to try something new." Since Maria is the opposite of timid, "audacious" must mean bold or daring.

Type 4: Synonym / Restatement Clues

The author uses a word or phrase nearby that means almost the same thing. For example: "The jubilant crowd cheered and celebrated wildly." The words "cheered" and "celebrated" tell you that "jubilant" means very happy or joyful.

The TACHS doesn't just test vocabulary words. It also tests your ability to understand figurative language, unusual expressions, and sentences that mean something different from what they seem. The diagram below shows three categories of tricky phrases and how to approach each one.

When you see a question on the TACHS that asks about meaning, first decide which category the phrase falls into. Then use the matching strategy from the chart above. This will help you eliminate wrong answers quickly.

Let's walk through a sample passage and question together, just like you would see on the TACHS.

Not every approach to these questions is equally effective. The table below compares helpful strategies with common mistakes students make. Knowing what to avoid is just as important as knowing what to do.

Figuring out the meaning of a phrase in context is a building block for even bigger reading skills. Once you master this, you will be ready for tasks like analyzing an author's argument or evaluating how word choice affects tone. The table below shows how this skill connects to what comes next.

In high school, you will be asked not just what a phrase means, but why the author chose that specific phrase. Every skill you build now makes those harder questions much easier later.

Try these five problems on your own. Each one gets a little harder. Read each passage carefully, find the context clues, and then check the answer.
