120 Third Grade Vocabulary Words with Meanings and Examples

Third graders meet more challenging words in stories, classroom directions, informational texts, and subject lessons. These words help children explain ideas, understand evidence, describe events, solve problems, and write with greater precision.

The 120 third grade vocabulary words below include academic language, reading terms, action verbs, emotions, descriptive words, and common terms from math, science, geography, and history. Each word has a simple meaning and a natural example sentence.

Vocabulary, Sight Words, and Spelling Words

These three word groups support different language skills.

Word group	Main purpose	Examples
Vocabulary words	Understand meanings and use words correctly	infer, fragile, typical
Sight words	Recognize common words quickly while reading	although, enough, through
Spelling words	Write words with correct letter patterns	suddenly, beautiful, carried
Academic words	Understand ideas and directions across subjects	evidence, determine, summarize
Subject words	Learn concepts from a particular subject	fraction, ecosystem, government

Vocabulary learning goes beyond recognizing or spelling a word. A child should understand what the word means, notice how it works in context, and use it accurately in speaking or writing.

Readers can use the surrounding sentence to choose the correct meaning.

Using Context Clues

Third graders often need to use clues across more than one sentence.

The path became steep. We leaned forward and took shorter steps as we climbed.

The second sentence shows that steep means rising sharply.

The bowl was fragile. Ben wrapped it carefully so it would not crack.

The words carefully and would not crack reveal that fragile means easily broken.

The forest looked gloomy. Thick clouds blocked the sunlight, and the trees appeared dark.

The description in the second sentence explains that gloomy means dark or lacking cheer.

Useful context clues include:

• definitions;
• examples;
• descriptions;
• actions;
• comparisons;
• contrasts;
• causes;
• results.

Choosing Better Words in Writing

Precise words help readers picture an event more clearly.

Basic paragraph:

We went up the big hill. I looked at the path. It was hard, but we kept going.

Improved paragraph:

We marched up the steep hill. I examined the narrow path ahead. Although the climb was difficult, our determined group continued toward the top.

The improved paragraph uses words that show exact movement, appearance, and attitude. However, the best word is not always the longest word. It should match the writer’s meaning.
