Precise and Formal Diction — Replace an informal or imprecise word with a more appropriate choice.

People have cared about choosing the right words for thousands of years. In ancient Greece, students studied rhetoric (the art of speaking and writing well). They learned that picking the perfect word could convince a crowd or lose an argument. The same idea is alive today on the SHSAT, where you need to spot weak or sloppy words and swap them for stronger, more exact ones.

So the big question is simple: How do you know when a word is too informal or too vague, and what do you replace it with? That is exactly what this lesson will teach you.

Before you can fix a word, you need to understand what makes it wrong in the first place. Two problems show up again and again on the SHSAT: a word is imprecise (too vague or general), or a word is informal (too casual for academic writing). Let's break down the main ideas.

Words live on a scale from super casual to very formal. The diagram below shows how the same idea can be expressed at different levels of formality. On the SHSAT, you almost always want to land in the formal and precise zone.

Notice how the words on the right side of the diagram are more specific and professional. The word "get" could mean almost anything — get a gift, get sick, get home. But "obtain" tells you exactly what happened. That's the power of precise diction.

When you see a diction question on the SHSAT, you can use a simple three-step process. Think of it as a checklist you run through every time you spot an underlined word or a multiple-choice option.

Here is how each step works in detail. In Step 1, you check whether the word sounds like something you'd say in a text message. Words like "gonna," "cool," "stuff," or "totally" are red flags. In Step 2, you ask if the word gives a clear picture. "Things" is vague. "Factors" or "elements" or "obstacles" each tells the reader something different and specific. In Step 3, you read the sentence in the passage. If the passage sounds like a science textbook, your replacement word should also sound like it belongs in a science textbook.

Certain informal words appear again and again in SHSAT passages. If you memorize their formal replacements, you'll save time on test day. The table below shows the most common swaps you should know.

Let's walk through a sample SHSAT-style question together. Read the passage sentence below and the four answer choices.

The SHSAT is designed to trick you. The test makers include wrong answers that sound fancy but don't actually fit. Below is a comparison of the most common traps and the strategies to beat them.

Precise diction isn't just a test skill — it's a life skill. In high school, college, and your career, the ability to pick the right word will set your writing apart. The table below shows how this skill connects to more advanced writing concepts.

Two advanced terms you'll hear later are denotation (the dictionary definition of a word) and connotation (the feelings or ideas a word carries). For example, "thrifty" and "cheap" both mean someone who doesn't spend much money. But "thrifty" has a positive feeling, while "cheap" sounds negative. On the SHSAT, this skill starts simply: pick the word that fits. In the future, you'll use it to shape how readers feel.
