Synonyms

Overview

Synonyms appears about 3.5 times per paper across the last four AFCAT solved papers, placing it in the highest weight band of English.

Synonyms carry an average of 3.5 marks per AFCAT paper, second only to reading comprehension within the English section. The format is fixed and brutally simple: a single stem word, four single-word options, no surrounding sentence, no clue about the register expected. The skill being tested is pure bookish-vocabulary recall under a 25 to 35 second budget per item.

The good news for AFCAT aspirants is that the paper draws from a fairly small and recognisable pool. The same families of words — abstract nouns of conflict, adjectives of moral colour, verbs of speech, Latinate descriptors of decay and excess — recur across the 2022, 2023, 2024 and 2025 papers. A focused list of about 250 stem-synonym pairs, drilled across six weeks and revised every Sunday, covers the bulk of what AFCAT throws at you.

This page gives you that list, organised by theme. Before the list, it walks through the four discrimination skills that turn a vocabulary item from a guess into a confident pick: part-of-speech matching, register and intensity, bookish versus everyday vocabulary, and root-cluster decoding. After the list, you get worked examples calibrated to the AFCAT trap-style, mnemonic strategies, and a clear time budget for paper day.

How AFCAT frames the question

The stem is one word; the options are four single words. There is no sentence, no governing clause, no hint about register. That makes the format pure recall — you either hold the word in your active vocabulary or you do not. The discrimination skill comes in only when two of the four options are close in meaning and you have to pick the one closest to the stem.

Across the four solved papers from 2022 to 2025, the stem distribution is roughly even between nouns, adjectives and verbs, with adjectives leading by a small margin. The stems are almost always single bookish words rather than common ones, because common words yield no useful discrimination.

• Noun stems tend to be abstract nouns of conflict, state or quantity. Examples in the AFCAT style: Dilemma, Tyranny, Scuffle, Brevity, Enigma, Discord, Contempt, Zenith.
• Adjective stems tend to carry moral or descriptive colour. Examples: Decrepit, Pernicious, Lucid, Capricious, Clandestine, Garrulous, Sagacious, Vivacious.
• Verb stems tend to be vivid action verbs that have a more common cousin. Examples: Blare, Entice, Vex, Cajole, Deride, Placate, Mitigate, Curtail.

The first move on any synonym item is to ask: what part of speech is the stem? If the stem is a noun, the right option must be a noun, even if a verb form of the same meaning is listed among the options. Match part of speech first; meaning second. This single discipline knocks out at least one and often two distractors on most papers.

Part-of-speech matching

Every English word carries grammatical baggage. A noun stem demands a noun synonym; an adjective stem demands an adjective. Mismatched parts of speech are not synonyms even when they share a meaning, and AFCAT distractors regularly exploit this.

Consider the stem Brevity. The dictionary meaning is shortness or conciseness. An option set might include: Short, Brief, Conciseness, Quickly. Three of those four — Short, Brief, Quickly — are adjectives or adverbs. Only Conciseness is a noun, and so only Conciseness is a true synonym of Brevity. The other three are eliminated on grammar alone, before meaning enters the picture.

Use this checklist at the start of every synonym item.

1. Identify the stem's part of speech. Most AFCAT stems end in tell-tale suffixes: -ity, -ness, -tion, -ance for nouns; -ous, -ive, -ent, -al, -ic for adjectives; -ate, -ify, -ise/-ize for verbs.
2. Scan the four options and flag any that do not share the stem's part of speech.
3. Eliminate those grammatically. Only then compare the meanings of the remaining options.

This discipline costs you about three seconds per item and saves you from the most common trap on the paper.

Register and intensity

This is the single most common AFCAT trap. Two options can be technically correct synonyms of the stem, but one matches the stem's register (formality) and intensity (force), and one does not. The matching option is the answer.

Register is the level of formality. Bookish, Latinate stems demand bookish, Latinate synonyms; everyday Anglo-Saxon stems can accept everyday answers. Intensity is the strength of feeling carried by the word. A mildly negative stem cannot have a maximally negative synonym, and a maximally negative stem cannot have a mild one.

When you are stuck between two close synonyms, ask: Is one option a sharper, more bookish version of the stem than the other? The sharper, more bookish option is usually the answer on AFCAT.

There is one important exception. If the bookish-looking option is actually a wrong meaning, register cannot rescue it. Register is a tie-breaker between two true synonyms, not a substitute for meaning. Always confirm that the option you are picking is a meaning-match before letting register decide.

Bookish vs everyday vocabulary

AFCAT stems are drawn almost exclusively from what one might call the bookish-vocabulary band: words you meet in editorial prose, formal speeches and literary criticism, but rarely in conversation. The right synonym usually sits in the same band. The wrong distractor is often an everyday, conversational word that captures the broad sense but misses the register.

To train your ear for the band, read editorial pages from The Hindu or The Indian Express for fifteen minutes a day. Highlight unfamiliar words, look up their meanings, and write a one-line gloss in your vocabulary notebook. Within four weeks you will find that you recognise — and predict — the AFCAT stem band without any conscious effort.

A second discipline is paraphrasing. When you meet a bookish word, force yourself to express its meaning in a single everyday English sentence. Doing so makes the word's true sense settle in your active vocabulary rather than your passive recognition store. Active vocabulary is what AFCAT tests.

A useful indicator: if you can think of a Latin or Greek root inside the stem, the stem is almost certainly bookish, and the answer is almost certainly bookish too. This brings us to root clusters.

Latin and Greek root clusters

A handful of productive roots cover a surprisingly large share of AFCAT vocabulary. Learn the root, and a single word teaches you a dozen. The table below lists twelve high-yield roots; commit them to memory in the first week of your prep.

Two prefixes are worth their own line because AFCAT uses them as discriminators. Bene- and mal- mean good and bad respectively; they let you decode any word with these prefixes even if you have never met it. Eu- (Greek, good) and dys- (Greek, bad) play the same role on the Greek side — eulogy is a good speech, dyslexia is a bad reading state, euphony is a good sound, cacophony is a bad one.

When you face an unknown stem, look for a root or prefix inside it. The decoded sense is rarely the precise meaning, but it is almost always close enough to eliminate two of the four options and turn a blind guess into a high-percentage pick.

High-yield AFCAT list — abstract nouns

This is the first of four themed tables that together form the AFCAT synonym core. Drill ten new pairs a day; revise the previous week's list on Sundays. By week six you should hold every pair on these four tables in active recall.

Abstract nouns dominate the noun-stem share of AFCAT synonyms. They name states, qualities, conflicts and conditions rather than physical objects.

High-yield AFCAT list — descriptive adjectives

Adjectives lead the AFCAT stem distribution. The list below covers moral colour (good, bad, deceitful), states of mind (calm, anxious, stubborn), and physical or social descriptors.

High-yield AFCAT list — action verbs

Verbs in AFCAT synonyms are typically vivid, single-syllable or two-syllable action verbs that have a more bookish cousin, or vice versa. Pay attention to whether the verb implies aggression, persuasion, reduction or release — that is usually how the distractors are framed.

High-yield AFCAT list — bookish bonus

This final table holds the bookish bonus words: stems that are less common, more Latinate, and frequently used as the trap-level item that separates a 28-mark English score from a 25. Drill these last, after the first three tables are solid.

Together with the abstract noun, adjective and verb tables above, you now have well over two hundred stem-synonym pairs in a single drill. Print these tables, fold them into a pocket-sized booklet, and run a column at a time during waiting moments — commute, queues, before bed. Spaced exposure is what fixes vocabulary in active recall.

Mnemonic strategies

Brute memorisation works only up to about a hundred words. Beyond that, you need techniques that build durable links between the word and its meaning. Three mnemonic methods work especially well for AFCAT-level vocabulary.

Sound-link mnemonics

Convert the unfamiliar word into a sound-alike English phrase that hints at its meaning. The link is silly on purpose; silly is memorable.

• Garrulous sounds like garrul-bus — picture a bus full of people who never stop talking. Garrulous means talkative.
• Vex sounds like vexed in Hindi cricket commentary when a batter is bowled out — annoy.
• Cajole sounds like ka-jol — picture coaxing someone the way the actress Kajol is coaxed in a film scene. Cajole means coax.
• Pernicious contains per and nice — but it is the opposite of nice, it is harmful right through. Pernicious means deeply harmful.

Root-based mnemonics

Decompose the word into its Latin or Greek root and learn the family together. One root gives you many words.

• Loquacious, eloquent, soliloquy all share loq- meaning speak. Loquacious is talkative, eloquent is well-spoken, soliloquy is talking to oneself.
• Magnanimous, magnify, magnate all share magn- meaning great. Magnanimous is great-souled (generous), magnify is to make great, magnate is a great person of industry.
• Veracity, verify, aver all share ver- meaning true. Veracity is truthfulness, verify is to confirm as true, aver is to declare to be true.

Sentence-image mnemonics

Build a short, vivid sentence that pictures the word in action. The image is what your brain stores; the sentence is just the scaffold.

• Decrepit: The decrepit jeep coughed once, then refused to start. Picture a rust-eaten 1950s jeep in a forgotten yard.
• Munificent: The munificent industrialist endowed a new wing to the hospital. Picture a marble plaque with the donor's name.
• Tyranny: The colony groaned under three centuries of tyranny. Picture a chained crowd watching a foreign flag rise.

Use whichever method clicks for a given word. Often the strongest hook is a mix — a root cue plus a vivid image plus a sound-link. The more associative paths a word has, the faster you retrieve it under exam pressure.

Time budget

AFCAT gives you 120 minutes for 100 questions, which is 72 seconds per item on average. The English section, with 30 questions, deserves about 30 to 35 minutes if you intend to finish the entire paper on time. Within English, the synonym block — 3 to 4 items — should consume no more than two and a half to three minutes.

That works out to about 35 to 50 seconds per synonym item. Use the budget as follows.

1. 0 to 5 seconds: Identify the stem's part of speech. Eliminate any option that does not match it.
2. 5 to 20 seconds: Recall the meaning of the stem. If you know it directly, identify the matching option among the survivors.
3. 20 to 35 seconds: If you do not know the meaning directly, look for a root or prefix inside the stem and decode an approximate sense. Eliminate options that contradict the decoded sense.
4. 35 to 50 seconds: If two options survive both checks, pick the one whose register and intensity match the stem. Mark and move on.

If at the 50-second mark you have no genuine pick — no positive recall, no root cue, no register signal — leave the item blank. AFCAT penalises wrong answers at minus one mark, and synonym items do not reward blind guessing. A blank costs zero; a wrong guess costs one. Three blanks in synonyms across the paper add up to nine wasted marks; three wrong guesses add up to three lost marks plus the nine wasted, for a net of twelve marks down.

Worked AFCAT-style examples

Exam-day strategy

1. Match part of speech first. If the stem is a noun, the right option must be a noun. Eliminate other categories before comparing meanings.
2. When two options are close in meaning, pick the one whose register and intensity match the stem. Bookish stems want bookish answers.
3. Use root clusters to decode unfamiliar stems. The twelve roots in the root-cluster table — bene-, mal-, loq-, magn-, ver-, aud-, vor-, cred-, fid-, anthrop-, biblio-, vac- — cover a large share of bookish vocabulary.
4. Drill twenty words a day from the four themed lists above; revise the previous week's words each Sunday. Spaced repetition is what fixes vocabulary in active recall.
5. Aim for 30 to 50 seconds per item in practice. AFCAT does not reward dwelling on a synonym item — either you have it or you move on.
6. Leave the item blank if you cannot eliminate at least two options. A blank costs zero; a wrong guess costs minus one and erodes confidence for the next item.
7. Read one editorial page from The Hindu or The Indian Express every day. Underline unfamiliar words, gloss them in a notebook, and add them to your weekly drill.
