4 Types of Context Clues

Context Clues Reference Chart

Use this chart to identify different types of context clues in reading passages!

Clue Type Signal Words Example
Definition is, means, refers to, called A herbivore is an animal that eats plants.
Example such as, for example, including Citrus fruits, such as oranges and lemons, are rich in vitamin C.
Contrast but, however, unlike, instead Unlike her gregarious sister, Maria was quiet and shy.
Inference (no signal words – use context) The aroma of fresh bread filled the kitchen. Everyone’s mouth watered.

Pro Tip

Always read the ENTIRE sentence (and sometimes the next sentence) to find context clues. Don’t guess from just one word!

Word Relationships

Understanding how words relate to each other helps you build a stronger vocabulary!

Types of Word Relationships

  1. Synonyms: Words with similar meanings (happy = joyful, glad, cheerful)
  2. Antonyms: Words with opposite meanings (hot ≠ cold, big ≠ small)
  3. Homophones: Words that sound the same but have different meanings/spellings (there/their/they’re)
  4. Homographs: Words spelled the same but have different meanings (bat = animal or sports equipment)

💡 Common Homophones on SEA:

Homophone Pair Meaning 1 Meaning 2 Example
there / their / they’re place possessive / they are They’re going over there to get their books.
to / too / two direction also / number I want to go too. That’s two tickets.
its / it’s possessive it is The dog wagged its tail. It’s a sunny day.
your / you’re possessive you are Your book is here. You’re doing great!
where / wear place to put on clothes Where should I wear this?

Prefixes, Suffixes & Root Words

Break down unfamiliar words into parts to decode their meaning!

📋 Common Prefixes:

Prefix Meaning Examples
un- not, opposite unhappy, unlock, unfair
re- again, back reread, return, rebuild
pre- before preview, pretest, preheat
dis- not, opposite disagree, disappear, dislike
mis- wrong, badly misunderstand, misbehave

📋 Common Suffixes:

Suffix Meaning Examples
-ful full of hopeful, careful, beautiful
-less without hopeless, careless, fearless
-er / -or one who does teacher, actor, worker
-tion / -sion action, state action, decision, celebration
-ly in a manner quickly, happily, carefully

Common Mistake

Don’t change the root word when adding suffixes! Example: happy + -ness = happiness (change y to i), NOT happyness.
