12.3 English Vocabulary, Idioms & Commonly Confused Words

Key Takeaways

  • Vocabulary questions draw from SSLC-level word lists covering synonyms, antonyms, one-word substitution, idioms, phrasal verbs, and commonly confused pairs; a daily ten-word habit with usage sentences is the fastest route to mastery
  • Commonly confused pairs (affect/effect, advice/advise, principal/principle, stationary/stationery) are distinguished by part of speech as much as meaning — learn the noun vs verb role for each
  • Reading comprehension is best approached by reading the questions first, skimming for the main idea, then scanning for keywords matching each question type (main idea, detail, vocabulary-in-context, inference)
  • Error spotting hinges on four checks: subject-verb agreement, tense consistency, article correctness, and parallelism across list items
  • Jumbled-sentence reordering relies on finding the topic sentence, following pronoun and transition-word links (however, therefore, moreover), and placing the concluding summary sentence last

Vocabulary: Synonyms, Antonyms, and One-Word Substitution

VAO Paper 2 often includes 5–10 vocabulary questions drawn from SSLC-level word lists. Build a daily habit of learning ten new words with their synonyms, antonyms, and a usage sentence.

  • Synonym — a word close in meaning: abundant ≈ plentiful, brave ≈ courageous, benevolent ≈ kind.
  • Antonym — a word opposite in meaning: generousstingy, ancientmodern, victorydefeat.
  • One-word substitution — replace a phrase with a single precise word:
    • "one who loves books" → bibliophile
    • "a person who cannot read or write" → illiterate
    • "the custom of having more than one spouse" → polygamy
    • "a speech made without preparation" → extempore
    • "a government by the people" → democracy
    • "the science of crop production" → agronomy
    • "a place where bees are kept" → apiary
    • "one who eats everything" → omnivore

Idioms and Phrasal Verbs

An idiom is a phrase whose meaning cannot be guessed from the individual words; a phrasal verb combines a verb with a particle (up, out, off, on) to form a new meaning.

Idiom / Phrasal verbMeaningExample
a piece of cakevery easy"The grammar section was a piece of cake."
once in a blue moonvery rarely"He visits the village once in a blue moon."
to turn a blind eyeto ignore deliberately"The officer turned a blind eye to the error."
break downstop working / collapse"The tractor broke down near the field."
give upstop trying / quit"Never give up on your preparation."
put offpostpone"They put off the meeting to next week."
look intoinvestigate"The Tahsildar will look into the complaint."
carry oncontinue"Carry on with your work."

Prefixes, Suffixes and Roots — How to Guess an Unknown Word

Vocabulary questions often use a word you have not met. Word parts let you make an informed guess rather than a blind one.

PrefixMeaningExample
anti-againstantiseptic, anticlimax
bene-goodbenevolent, beneficial
circum-aroundcircumference, circumvent
mal-badmalpractice, malnutrition
mis-wronglymisinterpret, misappropriate
pre- / post-before / afterprecede, postpone
sub- / super-under / abovesubordinate, supervise
trans-acrosstransfer, transparent
un- / in- / im- / il- / ir-notunauthorised, invalid, impartial, illegal, irregular
RootMeaningExample
audhearaudit, audience
dictsayverdict, dictate
script / scribwriteinscription, subscribe
spec / spectlookinspect, spectator
terrlandterritory, terrain
vid / visseeevidence, visible
jur / juslaw, rightjurisdiction, justice
cede / cessgo, yieldprecede, accession

Notice how many of these appear in revenue vocabulary: inscription, jurisdiction, territory, evidence, audit, accession. Learning the root gives you a family of words rather than a single one.

One-Word Substitution — A Working List

put up withto tolerate
give in / give up / give awayto yield / to abandon / to distribute or reveal
stand by / stand for / stand up toto support / to represent / to resist

The trap with phrasal verbs is that changing the particle changes the meaning completely: look after is not look into, and give up is not give away. Learn the verb-plus-particle as a single unit with one example sentence each.

Spelling and Confusable Plurals

Spelling Watch-List

Double-check these in cloze and editing questions: accommodation (double c, double m), committee (double m, double t, double e), privilege (no d), separate (par, not per), definitely (not "definately"), embarrass (double r, double s), liaison, necessary (one c, two s), occurrence (double c, double r, ending -ence), maintenance (not "maintainance"), acknowledgement, questionnaire, bureaucracy, surveillance, jurisdiction, beneficiary, receipt, grievance, tenant (not "tenent"), hereditary.

Irregular plurals that appear in error-spotting: criterion → criteria, phenomenon → phenomena, analysis → analyses, index → indices, appendix → appendices, sheep → sheep, deer → deer, mother-in-law → mothers-in-law, passer-by → passers-by, court martial → courts martial. Note the nouns that look plural but take a singular verb — news, mathematics, physics, politics, innings — and those that look singular but take a plural verb: cattle, police, people, poultry.

Exam Angle for Section 12.3

Vocabulary is the one part of the paper where a daily habit converts directly into marks. Ten words a day, each with a synonym, an antonym and a sentence, gives you roughly six hundred words over a preparation cycle — far more than the paper needs. Prioritise the confusable pairs and the one-word substitutions, because they are closed lists that recur, and treat idioms as a slower accumulation. When you meet an unknown word in the exam, use the prefix and root before you guess.
