Context clues for ASVAB Word Knowledge and reading
A context clue is a hint in the sentence or passage that tells you what an unfamiliar word means. Look for six kinds: a definition, a synonym, a contrast, an example, a cause or effect, and the general sense of the situation. Each has signal words that tell you where to look.
What are context clues and why do they matter on the ASVAB?
Context clues are the words around an unfamiliar word that let you work out its meaning. On the ASVAB they help twice. Word Knowledge measures the ability to pick the meaning of "words presented in context" (Official ASVAB: What to Expect), and Paragraph Comprehension often asks what a word means "as used in the passage." In both cases the sentence is evidence you can use.
Context will not always give an exact definition, but it usually tells you enough to remove two or three choices. Combined with word roots, it is often enough to answer a word you have never studied.
What are the six types of context clues?
Learn these six types and their signal words.
| Clue type | Signal words | Example |
|---|---|---|
| Definition or restatement | is, means, that is, in other words, or, commas, parentheses | The recruit was punctual, that is, always on time. |
| Synonym | and, also, likewise, similarly | The path was treacherous and dangerous after the ice storm. |
| Contrast (antonym) | but, however, unlike, although, instead, while | Unlike his reticent brother, Marco talked to everyone. |
| Example | such as, for example, including, like | She ordered provisions such as rice, beans and canned fruit. |
| Cause and effect | because, since, so, therefore, as a result | Because the bridge was precarious, the trucks took the long way. |
| General sense | no signal word; use the whole situation | After the grueling twelve-hour shift, he fell asleep in his chair. |
A semicolon or colon can also introduce a restatement, as in "He was laconic; he answered with one word."
How do you use a definition or synonym clue?
When the sentence restates the word, the restatement is your answer. Look for "that is," "or," "in other words," or a phrase set off by commas or parentheses right after the word.
Example: The recruit was punctual, that is, always on time. Punctual most nearly means: (A) polite (B) on time (C) neat (D) strong
- Spot the signal: "that is" introduces a restatement.
- Read the restatement: "always on time."
- Match: (B) on time.
- Substitute: "The recruit was on time." The meaning holds.
Answer: (B) on time.
Example: After the ice storm, the trail was treacherous and dangerous. Treacherous most nearly means: (A) beautiful (B) hazardous (C) crowded (D) long
- Spot the signal: "and" joins two words that describe the trail in the same way.
- The partner word is "dangerous," and the ice storm supports it.
- Match: (B) hazardous, which means dangerous.
- Reject: beautiful, crowded and long describe the trail in ways the sentence gives no reason for.
Answer: (B) hazardous.
How do you use a contrast clue?
When the sentence sets the word against something, the word means roughly the opposite of that something. Words like "unlike," "but," "however" and "although" are the signal.
Example: Unlike his reticent brother, Marco talked to everyone at the party. Reticent most nearly means: (A) talkative (B) reserved (C) angry (D) younger
- Spot the signal: "Unlike" means the brother is the opposite of Marco in this respect.
- Marco "talked to everyone," so the brother does not talk much.
- Match: (B) reserved, meaning quiet and not open with others.
- Reject (A): talkative describes Marco, which makes it the trap answer. Nothing suggests (C) or (D).
Answer: (B) reserved.
A contrast clue is the one most likely to produce a trap. The test writer often includes the word that describes the other side of the contrast. Make sure your choice describes the right person or thing.
How do you use example and cause-and-effect clues?
With an example clue, ask what the listed examples have in common. With a cause-and-effect clue, ask what kind of thing would cause that result or follow from that cause.
Example: The hikers packed provisions such as rice, beans and dried fruit. Provisions most nearly means: (A) tools (B) supplies of food (C) maps (D) rules
- Spot the signal: "such as" introduces examples.
- List them: rice, beans, dried fruit. All are foods that keep well.
- Generalize: the word means food or supplies for a trip.
- Match: (B) supplies of food.
Answer: (B) supplies of food.
Example: Because the old ladder was precarious, the painter refused to climb it. Precarious most nearly means: (A) unsteady (B) expensive (C) tall (D) borrowed
- Spot the signal: "Because" links the word to a result.
- Result: the painter refused to climb it.
- Ask what would make someone refuse to climb a ladder. It is unsafe or unsteady.
- Check: (C) tall might make some people nervous, but the most direct reason to refuse is that the ladder could fall. (B) and (D) are not reasons to refuse.
Answer: (A) unsteady.
What if there is no signal word?
Use the general sense of the situation: picture what is happening and ask what word would fit there. Then decide whether the word is positive or negative and how strong it is.
Example: After the grueling twelve-hour shift, he fell asleep in his chair. Grueling most nearly means: (A) exhausting (B) boring (C) well-paid (D) short
- No signal word, so picture the scene: a twelve-hour shift and falling asleep in a chair.
- Tone: a long shift that knocks you out is hard and tiring, a negative word.
- Remove (C) well-paid, a positive idea with no support, and (D) short, which contradicts "twelve-hour."
- Between (A) exhausting and (B) boring, falling asleep from tiredness fits exhausting better.
Answer: (A) exhausting.
How do context clues work across a whole passage?
In a reading passage the clue is often in a different sentence from the word, so read one sentence before and one after. Writers tend to explain a hard word somewhere nearby, especially when the word matters to the point of the paragraph.
Example: Passage: "The county had a contingency plan for the bridge. If the main span was closed, traffic would move to the old ferry road, and two extra buses would run. The plan had never been used until last winter's ice storm." As used in the passage, contingency most nearly means: (A) expensive (B) permanent (C) backup (D) secret
- The sentence with the word gives little help: "a contingency plan for the bridge."
- Read the next sentence: it describes what happens "if the main span was closed," a plan for a situation that may or may not happen.
- Read the last sentence: the plan "had never been used" until an emergency. That confirms it is held in reserve.
- Match: (C) backup. (B) permanent is the opposite of a plan kept for emergencies. Nothing supports (A) or (D).
Answer: (C) backup. A contingency plan is prepared for a possible future event.
When the sentence with the word gives no clue, do not guess yet. Read the sentences on either side first. The explanation is often one sentence away.
Which context clue mistakes should you avoid?
The most common mistakes are trusting a familiar meaning over the sentence, misreading the direction of a contrast, and choosing a word that fits the topic but not the slot.
- Familiar meaning wins over context. In "The clerk had to reconcile the two lists," reconcile means to make the records agree, not to make friends again. The topic (lists) tells you which sense is used.
- Contrast read backward. With "although," "unlike" or "but," the word means the opposite of the other side. Students often pick the word that describes the other side.
- Topic match without slot match. In a sentence about a storm, a choice like "windy" feels right because it fits the topic. Check whether it fits the exact place in the sentence and keeps the grammar.
- Ignoring strength. "Displeased" and "furious" both fit an upset customer, but if the customer "threw the receipt and shouted," the stronger word is the better match.
The fix for all four is the same: substitute your choice back into the sentence and read it as a whole. If it changes the meaning, the direction or the strength, keep looking.
How do you practice context clues for the ASVAB?
Practice by guessing before you look up. When you meet an unknown word while reading, write down your guess from context, then check a dictionary. Over a few weeks you will see your guesses get closer.
- Read short factual texts for 10 to 15 minutes a day.
- Underline any word you are unsure of and name the clue type that helps, if any.
- Write your guess, then check the meaning and note whether the clue type worked.
- Add the word, with the sentence where you found it, to your study cards. The vocabulary list is a good starting set.
- Practice with real-format items on the Word Knowledge page, then the context lesson.
Practice questions
Work each one on paper first, then open the explanation. These are original AptiStep items, not real ASVAB questions.
The old map was obsolete; in other words, it no longer showed the current roads. Obsolete most nearly means:
- out of date
- expensive
- hand drawn
- accurate
Show answer and explanation
Answer: A. out of date
The signal "in other words" introduces a restatement: the map no longer showed the current roads. That means it was out of date. Accurate is the opposite, and expensive and hand drawn describe the map in ways the sentence does not support.
Unlike her impulsive partner, Dana thought through every decision carefully. Impulsive most nearly means:
- careful
- acting without thinking first
- very intelligent
- easily tired
Show answer and explanation
Answer: B. acting without thinking first
Unlike signals a contrast. Dana thinks carefully, so her partner does the opposite: acts quickly without thinking. Careful describes Dana, not the partner, which makes A the trap. Nothing in the sentence supports intelligence or tiredness.
The kitchen stocked condiments such as mustard, ketchup and hot sauce. Condiments most nearly means:
- cooking tools
- main dishes
- sauces and seasonings added to food
- cleaning supplies
Show answer and explanation
Answer: C. sauces and seasonings added to food
The signal "such as" introduces examples. Mustard, ketchup and hot sauce are all things added to food for flavor, so condiments means sauces and seasonings. They are not tools, main dishes or cleaning supplies, which removes the other three choices.
Because the speech was so monotonous, half the audience fell asleep. Monotonous most nearly means:
- short
- loud
- shocking
- dull and unchanging
Show answer and explanation
Answer: D. dull and unchanging
Because links the word to the result: half the audience fell asleep. A dull speech delivered in an unchanging way puts people to sleep. The Greek parts agree: mono- means one, so the word suggests a single unchanging tone. Loud and shocking would keep people awake.
The two friends had an amicable talk and parted with a handshake. Amicable most nearly means:
- friendly
- brief
- angry
- secret
Show answer and explanation
Answer: A. friendly
The general sense helps: the people are friends and they part with a handshake, a peaceful ending. Amicable means friendly and without conflict. Angry contradicts the handshake, and brief and secret add details the sentence never gives.
The rookie was inept at first, but after a month of training she was one of the best on the crew. Inept most nearly means:
- confident
- unskilled
- late
- popular
Show answer and explanation
Answer: B. unskilled
But signals a contrast between the start and the end. After training she was one of the best, so at first she was the opposite: unskilled. Confident and popular do not contrast with being one of the best, and late has no support.
The trail guide was laconic; he answered most questions with a single word. Laconic most nearly means:
- friendly
- confused
- using very few words
- very talkative
Show answer and explanation
Answer: C. using very few words
The semicolon introduces a restatement: he answered most questions with a single word. That describes someone who uses very few words. Very talkative is the opposite. Friendly and confused describe attitude or understanding, which the sentence does not discuss.
Frequently asked questions
Do synonym-only Word Knowledge questions have context?
Not always. The official description includes both words in context and identifying "the best synonym for a given word" (officialasvab.com). For a bare word, use word roots and tone instead.
What if the context clue points to two choices?
Substitute both into the sentence and check strength and part of speech. The choice that keeps the exact meaning and intensity of the original sentence is the answer.
Are context clues enough without studying vocabulary?
They help a lot, but the more words you already know, the more of the sentence you understand, and the stronger the clues become. Combine both with the vocabulary list.
