14.4 Vocabulary: Synonyms, Antonyms, One-Word Substitution & Word Usage
Key Takeaways
- Vocabulary questions test a word's meaning in its sentence, so predict the meaning from context before reading the options.
- Near-synonyms differ in tone and strength: frugal and thrifty are approving, stingy is critical, and a slump is sharper than a dip.
- The prefix in- does not always mean 'not': inflammable means easily set on fire, and invaluable means extremely valuable.
- A temporary suspension of payments or of an activity is called a moratorium, and an asset pledged as security for a loan is called collateral.
- Commonly confused pairs such as stationary/stationery and principal/principle are frequent traps in error-spotting and filler questions.
14.4 Vocabulary: Synonyms, Antonyms, One-Word Substitution & Word Usage
Exam Focus: Vocabulary is tested directly (synonym and antonym questions, often tied to a reading passage) and indirectly (fillers, cloze tests, phrase replacement and word-usage items). SBI advertisement CRPD/CR/2026-27/17 sets Prelims English Language at 30 questions in 20 minutes and Mains General English at 40 questions in 35 minutes, so a strong working vocabulary saves time on every English question type.
1. The Context-First Method
- Read the whole sentence before looking at the options.
- Predict the meaning in your own words (for example, "strong and growing").
- Check the tone: positive, negative or neutral.
- Eliminate options with the wrong tone or the wrong part of speech.
- Substitute the remaining option into the sentence to confirm it reads naturally.
[!IMPORTANT] In passage-based vocabulary questions, the tested meaning is the meaning in that sentence. "Interest" can mean curiosity, a stake in something, or the price of borrowed money.
Worked Example: Synonym in Context
Sentence: "After two weak quarters, the bank's recovery drive finally gained traction as more borrowers resumed repayments."
Options: friction, momentum, attraction, resistance
- Predict: the drive "finally" started working, so the word means something like "progress".
- Tone: positive, because borrowers resumed repayments.
- Eliminate: "friction" and "resistance" are negative. "Attraction" looks similar but means being drawn towards something.
- Substitute: "gained momentum" reads naturally, so momentum is the answer.
"Attraction" shares the root tract (to pull) with "traction", which is exactly why it is there. Similar spelling is not similar meaning.
2. Roots, Prefixes & Suffixes
| Part | Meaning | Examples |
|---|---|---|
| bene- | good, well | benefit, benevolent, beneficiary |
| mal- | bad, badly | malpractice, malfunction, malicious |
| ante- | before | antecedent, antedate |
| post- | after | postpone, postdate |
| inter- | between | intermediary, interbank |
| trans- | across | transfer, transaction |
| cred | believe, trust | credit, credible, creditor |
| fisc | treasury, public money | fiscal, confiscate |
| pecun | money | pecuniary, impecunious |
| -cide | killing | pesticide, homicide |
| -ous | full of | prosperous, generous |
Using Roots on an Unfamiliar Word
- Impecunious = im- (not) + pecun (money) + -ous (full of). It means having little money, and its antonym is wealthy.
- Benefactor = bene (good) + fact (do or make) + -or (a person who). It means a person who gives money or help.
- Incredulous = in- (not) + cred (believe). It means unwilling to believe, and a close synonym is sceptical.
[!WARNING] False negatives: "in-" does not always mean "not". Inflammable means easily set on fire (the same as flammable), invaluable means extremely valuable, and infamous means well known for something bad. In formal usage, disinterested means impartial; the word for bored is uninterested.
3. High-Frequency Words With Synonyms and Antonyms
| Word | Meaning | Synonym | Antonym |
|---|---|---|---|
| Augment | increase in size or amount | boost | diminish |
| Curb | restrain or limit | restrict | encourage |
| Mitigate | make less severe | alleviate | aggravate |
| Bolster | support or strengthen | reinforce | undermine |
| Buoyant | strong and thriving (of markets or demand) | thriving | sluggish |
| Stringent | strict and exacting | rigorous | lenient |
| Prudent | acting with care for the future | sensible | reckless |
| Lucrative | producing much profit | profitable | unprofitable |
| Volatile | liable to change rapidly | unstable | stable |
| Resilient | able to recover quickly | tough | fragile |
| Impede | delay or block progress | hinder | facilitate |
| Scrutinize | examine closely | inspect | overlook |
| Ameliorate | make something better | improve | worsen |
| Exacerbate | make something worse | aggravate | alleviate |
| Frugal | sparing with money | thrifty | extravagant |
| Opaque | not transparent; hard to understand | unclear | transparent |
4. Connotation and Intensity: Choosing Between Near-Synonyms
Two options can share a dictionary meaning yet differ in connotation (the approving or critical feeling a word carries) or intensity (how strong it is). The correct option matches the sentence on both.
| Core idea | Mild or approving | Strong or critical |
|---|---|---|
| Careful with money | thrifty, frugal | stingy, miserly |
| Sure of oneself | confident | arrogant |
| Holding to a view | firm, determined | obstinate, stubborn |
| Wanting to know | curious | nosy, prying |
| A fall in prices or sales | dip, decline | slump, crash |
| A rise in prices or demand | rise, uptick | surge, spike |
Exam use: If a sentence says demand "did not just rise, it ___", the blank needs a word stronger than "rise", such as "surged". If a passage praises a careful saver, "frugal" fits and "miserly" does not.
5. Antonym Questions: Finding the True Opposite
- Fix the sense used in the stem or passage first.
- Form the opposite in the same part of speech, so an adjective needs an adjective.
- Reject options that are only related to the word rather than opposite to it.
| Stem word (sense) | True antonym | Tempting wrong options | Why they fail |
|---|---|---|---|
| Lucrative (profitable) | unprofitable | expensive, risky | linked to money, but not opposite in meaning |
| Liquid, of an asset (easily turned into cash) | illiquid | solid, gaseous | opposite of a different sense, the physical state |
| Sanguine (optimistic) | pessimistic | bloodless, calm | "bloodless" plays on the Latin root for blood; "calm" is unrelated |
| Candid (frank) | evasive | blunt, sugary | "blunt" is a near-synonym; "sugary" plays on the look-alike "candy" |
6. One-Word Substitution
| Description | One word |
|---|---|
| A person or firm unable to pay debts | Insolvent |
| An official examination of accounts | Audit |
| Dishonest use of money entrusted to one's care | Embezzlement |
| A temporary suspension of an activity or of payments | Moratorium |

7. Word Usage: Same Word, Different Senses
Mains papers can ask which sentences use a word correctly and meaningfully. Test each sentence for the right part of speech, the right grammatical pattern and a natural meaning.
| Word | Sense 1 | Sense 2 | Sense 3 |
|---|---|---|---|
| Charge | The bank levies a processing charge. (fee) | He faced a charge of forgery. (accusation) | She took charge of the branch. (responsibility) |
| Interest | The loan carries 9% interest. (price of borrowing) | He showed interest in the scheme. (curiosity) | Directors must disclose any interest in the deal. (stake) |
| Security | Gold was offered as security. (collateral) | Government securities trade in the bond market. (instrument) | The branch tightened security. (safety) |
Worked Example: Correct and Meaningful Usage
Question: In which of the following sentences is the word "charge" used correctly?
- (i) The bank will charge a fee for issuing a duplicate passbook.
- (ii) The deputy manager was in charge of the currency chest.
- (iii) The customer charged of the delay at the counter.
Analysis: Sentence (i) uses "charge" as a verb meaning "ask a price", which is correct. Sentence (ii) uses the fixed phrase "in charge of", meaning responsible for, which is also correct. Sentence (iii) fails because "charge" does not take "of" to mean complain; the writer needed "complained about". The answer is (i) and (ii) only.
8. Commonly Confused Words
| Pair | Meanings |
|---|---|
| principal / principle | main sum or head of an institution / a basic rule |
| stationary / stationery | not moving / writing materials |
| affect / effect | to influence (verb) / a result (noun) |
| complement / compliment | something that completes / praise |
| adverse / averse | unfavourable / unwilling |
| precede / proceed | come before / go ahead |
| council / counsel | a body of people / advice, or a lawyer |
| economic / economical | relating to the economy / thrifty, not wasteful |
9. Building Vocabulary Before the Exam
- Read in the exam's register. Banking, economy and current-affairs writing uses the formal words (curb, bolster, moratorium, prudent) that bank-exam passages and fillers rely on.
- Log each new word in five fields: part of speech, meaning in context, one synonym, one antonym and a sentence of your own.
- Group words by root. Learning cred once gives you credit, credible, creditor and incredulous together.
- Revise on a spaced schedule, for example on day 1, day 3 and day 7. Retire a word only after you have recalled it correctly three times.
- Practise under the real clock. Prelims English allows about 40 seconds per question (20 minutes for 30) and Mains General English about 52 seconds (35 minutes for 40). A direct vocabulary item should take well under that average, leaving time for reading comprehension.
Common Traps
- Choosing a dictionary synonym that does not fit the sentence's context.
- Missing the word "opposite" in antonym question stems.
- Picking the right meaning in the wrong part of speech, such as "prudence" where an adjective is needed.
- Picking a near-synonym with the wrong tone or strength, such as "miserly" for a careful saver.
- Reading every "in-" word as a negative, such as taking "invaluable" to mean worthless.
- Choosing an option that looks like the stem word, such as "attraction" for "traction", instead of one that means the same.
