CONTEXT CLUES – Complete Guide for ATI TEAS

Why Context Clues Matter on TEAS

The English & Language Usage and Reading sections often ask you to determine the meaning of an unfamiliar word using surrounding text. You do not need a dictionary. You need to recognize how the author signals meaning.

TEAS Skill: Identify the type of context clue and use it to define a word, choose a synonym, or complete a sentence.

The 4 Main Types of Context Clues (TEAS-tested)

Type	Signal	Example
Definition	The meaning is given directly, often with commas, dashes, or "is/are/means."	He was emaciated, or extremely thin.
Synonym	A similar word or phrase appears nearby.	The tumultuous crowd was loud and chaotic.
Antonym	An opposite word or phrase appears nearby (often with unlike, but, however, whereas).	Unlike his placid sister, he was agitated.
Example	Specific examples help you infer the general meaning.	Nocturnal animals, such as bats and owls, are active at night.

Note: Some TEAS prep materials also list Inference (cause/effect or logic) as a 5th type, but it overlaps with example/synonym. We will focus on the 4 clear types above.
