Inference

Master the art of unlocking unknown words by reading the clues an author hides in every sentence.

ISEE Middle Level Reading Comprehension

What Are Context Clues?

When you encounter an unfamiliar word while reading, the surrounding text almost always offers hints about its meaning. These hints are called context clues: the words, phrases, and sentences that surround an unknown word and help you figure out what it means.

Why They Matter on the ISEE

Vocabulary-in-Context

The ISEE asks "the word ___ most likely means..." without providing a dictionary.

Inference Questions

Many questions require you to infer meaning from clues rather than find a direct statement.

Speed Advantage

Context-clue skills let you answer quickly without second-guessing unfamiliar words.

The Five Types of Context Clues

Definition & Synonym Clues

Antonym & Example Clues

The Inference Clue

The most common type on the ISEE: no definition, no synonym, no obvious opposite. Instead, you must combine multiple pieces of information from the surrounding sentences to reason out the meaning.

Definition vs. Inference

	Definition Clue	Inference Clue
Signal words	"is," "means," "or," dashes	None: meaning is implied
Where to look	Same sentence	Surrounding sentences
Difficulty	Easier	Harder
ISEE frequency	Occasional	Very common
Strategy	Spot the signal, read definition	Read around, combine clues, substitute

Signal Words Cheat Sheet

Definition / Synonym

"is," "means," "or," "that is," "in other words," "also known as," commas, dashes, parentheses

Antonym / Contrast

"but," "however," "unlike," "instead of," "although," "on the other hand," "whereas"

Example

"such as," "for example," "including," "like," "for instance," "especially"

The 4-Step Method

1

Locate the unknown word and read the full sentence it appears in.

2

Read around: read at least one sentence before and one sentence after.

3

Predict: cover the word and guess a meaning that fits the context.

4

Substitute: plug your guess into the sentence. If the sentence still makes sense, choose the matching answer.

Example 1: Definition Clue

1

Locate: The unknown phrase is "habitat."

2

Read around: Right after the comma, the author writes "the natural environment in which it lives and grows."

3

Predict: "Habitat" means the place where an organism naturally lives.

4

Substitute: "The biologist studied the organism's natural living place." ✓ It fits perfectly.

Example 2: Antonym Clue

1

Locate: The unknown word is "convoluted."

2

Signal word: "While" signals a contrast between the two experiments.

3

Predict: "Straightforward" means simple, so "convoluted" must mean the opposite: complicated.

4

Substitute: "The second proved to be quite complicated." ✓ Makes sense.

Example 3: Inference Clue

1

Locate: The unknown word is "conserve."

2

Read around: No rain for months, crops dying, reservoir nearly empty: there is a shortage.

3

Predict: If water is scarce, officials would want people to save or use less water.

4

Substitute: "Officials urged residents to save water." ✓ Logical fit.

Common Mistakes

✕ Guessing from the Word Alone

Ignoring the passage and guessing a meaning based on how the word "looks" or "sounds." Always read the surrounding text first.

✕ Reading Only the Target Sentence

Many inference clues live in the sentence before or after. If you stop at one sentence, you miss the most important hints.

✕ Skipping the Substitute Step

Picking an answer without checking whether it actually fits the sentence. Always plug your choice back in and re-read.

Summary of Clue Types

Clue Type	What to Look For	Example Signal
Definition	Meaning given directly	"is," commas, dashes
Synonym	A similar word nearby	"or," "in other words"
Antonym	An opposite word nearby	"but," "unlike," "however"
Example	Illustrative list	"such as," "including"
Inference	Combine surrounding details	No single signal word

Question 1 of 5

"The artist was known for her prolific output. In a single year, she completed forty paintings, illustrated two children's books, and designed the murals for the new library."

▼ Tap to read passage

As used in the passage, the word "prolific" most likely means:

The passage lists forty paintings, two illustrated books, and murals: all in one year. This enormous output is the example clue telling you "prolific" means producing a large amount of work.

Question 2 of 5

"Although the coach expected a lackadaisical performance after the long break, the team sprinted onto the field with tremendous energy and focus."

▼ Tap to read passage

The word "lackadaisical" most likely means:

"Although" signals a contrast. The team actually showed "tremendous energy and focus," so the expected performance was the opposite: lacking enthusiasm or effort. This is an antonym clue.

Question 3 of 5

"The once-busy factory now stood derelict. Windows were shattered, weeds pushed through cracks in the floor, and the roof had partially collapsed."

▼ Tap to read passage

Based on the context, "derelict" most likely means:

The inference clues: shattered windows, weeds growing through the floor, a collapsed roof: all point to a building that has been abandoned and is falling apart. No single signal word appears, so you combine the details.

Question 4 of 5

"Maria was a novice at chess. She had only learned the rules the week before and still confused the movements of the bishop and the knight."

▼ Tap to read passage

The word "novice" most likely means:

The clues are: "only learned the rules the week before" and "still confused the movements." Both details show someone new and inexperienced. "Novice" means a beginner with little experience.

Question 5 of 5

"The diplomat's candid remarks surprised everyone. Instead of giving the usual polished, carefully worded speech, she spoke openly about the failures of the peace talks."

▼ Tap to read passage

Which type of context clue best helps you understand the meaning of "candid"?

"Instead of" is a contrast signal. The passage contrasts "polished, carefully worded" with "spoke openly," telling you "candid" means the opposite of guarded. This is an antonym clue.
