Confused About When to Use Underline, Highlight, or Circle While Taking Notes
I'm studying for my English exam and I keep seeing instructions that say to underline, highlight, or circle words or phrases in texts. I'm not sure if there's a rule for which one to use for different purposes. For example, should I underline key vocabulary, highlight important dates, and circle grammar errors? Or is it just personal preference?
Here are a few cases I'm working with:
- In the sentence "The cat sat by the window," my teacher says to underline the verb. Should I highlight it instead?
- In my notes, I circled 'however' in a sentence, but my friend highlighted it. What's the difference?
I'm trying to make my notes clearer but I'm getting confused about which marking to use and when.
Context:
Preparing for a high school English exam in the US.
What to Know
| What to Know | Why It Matters | Example | Quick Check |
|---|---|---|---|
| When taking notes, it's helpful to use consistent marking patterns so your notes stay organized and easy to review. | If you notice you’re using the same marking for everything, pause and ask yourself: What is the main point? | I used "underline" because it matched the meaning in my sentence. | Does this sentence need underline or highlight based on my intended meaning? |
| Circle for errors (like grammar mistakes) or discourse markers (e.g., words showing contrast or sequence). | This helps you choose wording by meaning instead of surface form. | I used "highlight" because the context required that meaning. | Did I choose this form for meaning, not because it looked familiar? |

When taking notes, it's helpful to use consistent marking patterns so your notes stay organized and easy to review. Here’s a common, effective approach you can adopt:
Patterns to try:
- Underline for verbs, key vocabulary, or specific items you’re analyzing in detail.
- Highlight for main ideas, crucial facts, or especially important information.
- Circle for errors (like grammar mistakes) or discourse markers (e.g., words showing contrast or sequence).
Compare these examples:
- In "She quickly ran to the store," you might underline "ran" (the verb). If the main idea is going to the store, highlight the entire phrase "ran to the store."
- In the sentence "First, you mix the eggs," circle "First" to draw attention to its function as a transition word; highlight "mix the eggs" as a critical step in a process.
Self-check:
Try marking up this sentence in your notes:
"Although it was raining, Sam finished the race."
- Which mark would you use for "Although"? For "finished"?
Corrective tip:
If you notice you’re using the same marking for everything, pause and ask yourself: What is the main point? Am I drawing the right attention to each type of information?
There’s no universal rule for when to underline, highlight, or circle, but making intentional choices clarifies your notes. Here’s how these strategies typically compare:
- Underline highlights items within sentences you want to study closely (like parts of speech).
- Highlight calls attention to content-level ideas, facts, or themes—things you need to remember at a glance.
- Circle makes specific words stand out visually when reviewing for a targeted purpose, such as linking signal words, errors, or patterns.
Example A (Underline vs. Highlight):
- For the sentence, "Every dog barked loudly," underlining "barked" (verb) shows grammatical focus. Highlighting "Every dog" denotes importance for meaning.
Example B (Circle vs. Highlight):
- In "Nevertheless, he tried again," you might circle "Nevertheless" to analyze its connecting function, while highlighting "he tried again" as the key event.
Practice prompt:
Try marking up this sentence: "Because she studied hard, Lisa improved." Underline the verb, highlight the main idea, and circle the connector.
Self-edit tip:
If your notes feel cluttered, consider if each marking adds value—or if sticking to one purpose for each (e.g., always circling connectors) will help you study more effectively.
Some teachers or textbooks set guidelines (or protocols) for how to mark texts, but if no protocol is given, set your own consistent system to avoid confusion.
Suggested Marking Protocol:
- Underline: Use for target grammar (e.g., all prepositions, or all verbs in a text).
- Highlight: Use for essential facts, dates, main concepts—anything to revisit quickly.
- Circle: Use for unusual, confusing, or error-prone elements, such as new conjunctions, signal words, or mistakes you want to fix.
Protocol in action:
- "The quick fox leaped over the lazy dog." (Underline "leaped"; highlight "quick fox" if it's important; circle "over" if you're studying prepositions.)
- "In addition, she excels at math." (Circle "In addition" as a signal phrase; highlight "excels at math" as a main idea.)
Practice step:
Set a short marking key for your next page of notes (list what you’ll underline, highlight, and circle). Pause after one page to see if your markings are easy to follow.
Feedback:
If you find you’re swapping highlight and underline randomly, pause and re-read your key. Adjust so every mark type links to a clear purpose.
