Language Arts 8 - 11/4/2024

Today's goals:

• Use Context Clues to figure out the meaning of unknown words

• Introduce Roots and Affixes

• Use these concepts in our own writing

Context Clues

You may see a word you don't know when reading a story.
How can you figure out what this new word means?

You could try using context clues.

""Context" happens when the other words in a sentence help give a specific word meaning. Readers use the context clues in each sentence to determine the meaning of the underlined word.

5 Main Types of Context Clues

• Definition clues - Word is defined directly

• Synonym clues - Word has a similar meaning to what is described

• Antonym clues - Word has an opposite meaning to what is described

• Example clues - Examples of word is included in the sentence

• Inference clues - Use clues and text evidence to find definition
