Vocabulary: Synonyms, Antonyms and Meanings

Synonyms of advanced vocabulary

A synonym question gives you one difficult word and asks for the option closest in meaning. The task tests whether you know the core sense of the word, its connotation (positive, negative or neutral), and its register (formal or informal). Many distractors are not wrong in every sense but are wrong in the sense the word carries in context. A reliable method is to (1) decide whether the word describes an action, a quality, a person or a thing, (2) recall its core meaning in one short phrase, (3) remove any option that is an antonym, and (4) choose the option that matches the core meaning most precisely.

Several patterns recur in CDS papers. First, a word may have a general meaning and a specialised one. For example, mensuration in mathematics means the measurement of length, area and volume, so the nearest synonym is measurement rather than any general word for a lesson or a question.

Second, pairs of words that look alike often differ in degree or in the kind of situation they describe. Use the following groups as a guide.

• Commotion — a noisy, confused disturbance. Uproar is its closest synonym because it denotes a loud and violent disturbance. Peace is its antonym.
• Inherent — existing as a natural and essential part of something. Inbuilt carries the same sense of a permanent, built-in feature.
• Reprimand — to rebuke formally for wrongdoing. Admonish means to warn or reprove in the same way. Praise and appreciate are opposites.
• Perpetual — continuing forever without end. Everlasting is the synonym. Temporary is the antonym, while powerful and persuasive describe force rather than duration.
• Exemplify — to show by example. Demonstrate is the nearest synonym, since it means to make something evident by showing it. Devise means to plan and sympathize means to feel concern for others.
• Crux — the decisive or most important point of a matter. Core is its closest synonym. Part, idea and tip capture only minor senses.
• Competency — the ability to perform a task effectively. Capability is the synonym. Knowledge means information held, and it does not by itself mean the power to act.
• Haughty — showing disdain for others out of pride. Arrogant is the synonym. Modest is the antonym, and tough or knowledgeable are unrelated.
• Industrious — hard-working and steady in effort. Diligent is the synonym. Indolent, meaning lazy, is the antonym.
• Indignant — angry at something considered unjust. Resentful is the nearest synonym. Congenial and supportive are opposites in attitude.
• Drown — to die by being submerged in liquid. Submerged is the nearest synonym in the sense of being placed under water, while swam, floated and swarmed describe different actions.
• Dry (of a season or climate) — having little rain or moisture. Arid is the synonym. Humid, moist and rainy describe the presence of water, so they are opposite in sense.
• Differences (between people) — disagreements in opinion. Discrepancies is used for mismatched facts or figures, so it is narrower here.
• Hinder — to obstruct or delay. Impede is the synonym. Facilitate, meaning to make easier, is the antonym.
• Complexity — the state of having many interconnected parts. Intricacy is the synonym. Grievance, complacency and conclusion are unrelated.
• Excessive — more than is normal or reasonable. Inordinate is the synonym. Inculpable (blameless) and innocuous (harmless) look like synonyms but do not express quantity.
• Initiate — to begin or start. Began is the closest synonym. Ordered, interfered and planned describe other actions.
• Pale (after illness) — lacking colour in the face. Sallow means having an unhealthy, yellowish pallor. Ruddy, glowing and radiant describe healthy colour and are opposites.
• Overrule — to reject a proposal by higher authority. Veto is the synonym. Wan, weaken and supersede carry different senses.
• Shock (emotionally) — to cause horror or dismay. Appalled is the synonym. Pacify, meaning to calm, is the opposite.
• Conversational (of language) — relaxed and everyday. Informal is the synonym. Formal is the antonym.
• Malicious — wishing harm to others out of ill will. Spiteful is the synonym. Generous, affectionate and magnanimous describe kind qualities.
• Designation — a formal title or post held by a person. Position is the nearest synonym in this sense.
• Endearment — an affectionate expression. Fondness, meaning tender liking, is the synonym.
• Forbearance — patient self-control that holds back from reacting. Restraint is the synonym. Constraint is an external limit rather than a self-chosen quality.
• Gibbous — rounded or humped in form. Hunched, meaning bent over, is the nearest synonym.
• Torment — to cause severe mental suffering. Distress is the synonym. Cajole, meaning to coax, has the opposite effect.
• Peerless — having no equal. Unequalled is the synonym.
• Smother (fire) — to suppress or extinguish by cutting off air or covering. Douse, which means to drench and put out, is the closest option here. Light, surround and saw do not express extinguishing.
• Harbinger — a forerunner that announces what is to come. Advance messenger is the nearest synonym. Ancestor and overlooking are unrelated.
• Vista — an extensive view, especially of scenery. Landscape is the closest synonym. Location, feature and vitality do not describe a view.
• Lamentable — deserving regret or condemnation. Deplorable is the synonym. Acceptable and permissible are opposites in sense.
• Endurance — the ability to persist through hardship. Patience captures the steady perseverance sense. Success is the result of endurance, not the quality itself.
• Jaunt — a short pleasure trip. Expedition is the closest choice among the options, since it denotes a journey made for a purpose.

When two options both seem possible, prefer the one that matches the word's connotation and register. Avoid choosing a word that is merely related to the topic, such as a word about appearance when the question asks for a synonym of a word describing a physical shape.

Antonyms of advanced vocabulary

An antonym question asks you to find the word whose meaning is the reverse of the target word. In advanced vocabulary tests, the options usually include a synonym, a near-synonym, and a word from a related field, so only one choice is a true opposite. The reliable method is to fix the exact sense of the target word in its context, then ask what state, action, or quality would reverse it. Many words are context-sensitive, so the sense in the sentence matters more than the most common dictionary meaning. A word is not the antonym merely because it sounds negative or belongs to the same topic. Check whether the option is a genuine reversal or only shares the same tone.

Many antonym items involve verbs and states of mind. Solace is comfort in distress, and its reversal is aggravation, which means making distress worse. Spontaneous means arising naturally, so its direct opposite is deliberate, meaning intentional and planned. To assert is to state something firmly, and its opposite is to deny, meaning to declare that something is not true. To exonerate is to clear someone of blame, and its reverse is to convict, meaning to find someone formally guilty. To persuade is to induce belief or action, whereas to discourage is to cause someone to lose the will to act. To cherish is to hold something dear, and to deprecate, meaning to express strong disapproval of it, reverses that attitude. To chide is to scold, and to commend is to praise. To discontinue is to stop, and to resume is to start again after an interruption. Despair is a state of hopelessness, and its reversal is elation, meaning great joy or high spirits. To accuse is to charge someone with wrongdoing, and to vindicate is to clear someone of blame or show that they were justified. To boast is to speak with excessive pride, and to deprecate, meaning to belittle, is its reverse. To originate is to come from a source, while to culminate is to reach a final end point. To detain is to hold someone in custody, and to release is to set them free. To blend is to mix things into one mixture, and to separate is to divide them into parts. Malicious means intending harm, and benevolent means well-meaning and kind. Disdainful means regarding someone as beneath notice, and respectful, meaning showing esteem, is its opposite. Frugal means sparing in the use of money or food, and extravagant, meaning wasteful or lavish, is its opposite.

Adjectives and nouns of quality and degree form the next group. Hilarious means extremely funny, and its opposite is serious, meaning without humour. Pandemonium means wild disorder and noise, and its reverse is peace, meaning calm and quiet. Eccentric means deviating from what is usual, and normal means conforming to the standard. Distinctive means clearly different from others, and common means found widely and not special to one place. Chaos is complete disorder, and its antonym is order, meaning proper arrangement. Contrary means opposed to something, so its antonym is similar, meaning alike or in agreement. Considerable means large in amount or degree, and trifling means small or unimportant. Dormant means inactive or resting, and its opposite is active, meaning engaged in action. Brevity means using few words, and its opposite is verbosity, meaning the use of more words than necessary. Celestial means belonging to the heavens or divine, and earthly means belonging to the material world. Itinerant means travelling from place to place, and settled means living permanently in one place.

Descriptions of people form another important group. Erudite means learned and widely read, and its antonym is ill-educated, meaning lacking education. Particular means giving close attention to detail, so its opposite is vague, meaning not exact or careless about detail. Paunchy means having a protruding belly, and slim means having a trim, thin figure. Reticent means disinclined to speak, and garrulous means excessively talkative. Childish means immature, and seasoned, meaning experienced and mature through long exposure, is its opposite. Magniloquent means using grandiose, high-flown language, and terse means brief and concise. Clandestine means done in secret, and conspicuous means easily seen or obvious.

Several traps recur across these items. A word that looks like a negative form is not automatically the antonym, so check the meaning rather than the prefix alone, although the prefix ill- in ill-educated does reverse the sense. A word that sounds opposite but is only a related notion, such as deter for discourage or uniformity for chaos, is not the correct answer. Finally, a word that means the same as the target, such as precise for particular or learned for erudite, is a synonym and must be eliminated. Learn each target word with its best opposite, not only with its definition, because the exam tests the reversal directly.

Synonyms of advanced vocabulary

Synonym questions ask you to replace a difficult word with the word whose meaning is closest to it in the same sentence. A synonym is a word that means nearly the same as another word, and an antonym is a word with the opposite meaning. Examiners often include distractors that are real words from the same topic or the same word family, so an option should not be chosen just because it sounds related. Choose the option whose core meaning matches the underlined word in that sentence.

A reliable method has four steps. First, identify the part of speech of the underlined word, because a verb must be replaced by a verb and an adjective by an adjective. Second, state the core meaning of the word in plain language. Third, substitute each option into the sentence and check that the meaning is preserved. Fourth, reject options that are antonyms or that share only a general theme with the target word.

• anxious (for) — in the sense of strongly desiring something, not worrying. Its synonym here is eager. Example: She was anxious for news of the result, meaning she was eager to hear it.
• circumscribe — to limit or restrict within definite bounds. Do not confuse it with circumvent, which means to find a way around a rule or obstacle. Example: The powers of the committee are circumscribed by the constitution.
• eavesdrop — to listen secretly to a conversation or sounds that others do not know are being heard. Example: He was caught eavesdropping on the staff meeting.
• exhort — to urge or strongly encourage someone to take a particular action. Example: The general exhorted his troops to hold the bridge.
• hospitable — friendly and generous toward guests or strangers. Cordial, meaning warm and welcoming, is its nearest synonym. Surly and frosty are its opposites in tone. Example: The villagers were hospitable to every visitor.
• incongruous — out of keeping with the surroundings or the time, so unsuitable for them. Inappropriate is the nearest synonym. Example: A horse-drawn cart looked incongruous on the motorway.
• mercurial — changing quickly and unpredictably, especially in mood. Volatile carries the same sense of sudden, unpredictable change. Example: Her mercurial moods made planning difficult.
• obligatory — required by rule or duty and not left to choice. Essential is the nearest synonym in this sense. Voluntary, elective and optional are its opposites. Example: Safety training is obligatory for new recruits.
• predisposition — a tendency or susceptibility to something. In this sense vulnerability is the nearest synonym, since it means being open to harm. Immunity and resistance are opposites, because they mean protection against something. Example: A predisposition to asthma runs in his family.
• sardonic — mocking, scornful or grimly sneering in manner. Mocking is its synonym in a smile or remark. Respectful and deferential are opposite in tone. Example: He gave a sardonic reply to the proposal.
• resistance — opposition to control or domination. Defiance means open refusal to submit to authority, so it is the closest synonym in this sense. Conforming is the opposite. Example: The villagers showed resistance to the new rules.
• utopian — describing an imagined perfect state or plan that is idealistic but impractical. Among ordinary options, ideal is the nearest in meaning, while realistic and practicable are opposites. Example: Her plan to end poverty in a year is utopian.
• nugatory — of no value, futile or having no effect. To render something nugatory is to make it ineffective. Ineffectual is its nearest synonym. Explicit and implicit concern clarity of expression, not effect. Example: A small budget rendered the scheme nugatory.
• convulse — to shake or jerk violently and involuntarily. Among plain options, shiver, meaning to tremble or shake, is the nearest sense. Crouch describes a posture, not a shaking. Example: The patient convulsed on the bed before becoming still.
• complacent — self-satisfied and unaware of possible problems. Contented, meaning satisfied and at ease, is the nearest option, but complacent carries a negative sense of failing to notice danger. Discontented is the opposite. Example: Success can make a company complacent.
• derisory — so small or inadequate as to be ridiculous or not worth taking seriously. Inadequate is the nearest synonym. Do not confuse it with derogatory, which means insulting or disparaging in language. Example: The compensation offered was derisory for such a loss.
• defuse — to calm a tense situation or reduce its danger. Mitigate, meaning to make less severe, is the nearest synonym. Mediate means to act as an intermediary, which is a different process. Example: A quick apology defused the quarrel.
• flounder — to struggle and make little progress, often because of difficulty. Faced many problems is the nearest sense. Glide through and float through, meaning to pass without difficulty, are opposites. Example: The startup floundered once its funding ended.
• brevity — shortness of expression, saying much in few words. Concision has the same meaning. Lengthiness is its opposite. Example: The brevity of the notice made it easy to read.
• obtuse — slow to understand or perceive, that is, dull or stupid in understanding. Dull is its synonym. Sensitive and quick-witted are opposites. Example: He was too obtuse to notice the warning signs.
• transpire — to become known or come to light. In this sense it is a synonym of emerge, as in it transpired that. Exchange and merge do not carry the meaning of coming to light. Example: It later transpired that the report had been altered.
• exhilarating — causing excitement, elation or high spirits. Thrilling has the same meaning. Peaceful and prominent do not describe excitement. Example: The rally ride was exhilarating.
• decapitate — to cut off the head of a person. Behead is its exact synonym. Dismiss means to remove from a post or reject a case, and discharge means to release, so neither describes cutting off a head. Example: The sword was used to decapitate the prisoner.
• dingy — dull, drab and dirty, usually because it is dark or badly kept. Dark and dirty conveys both senses. Pale describes only a lack of brightness, and cloudy and hazy describe weather or vagueness. Example: The dingy corridor had peeling paint.
• fastidious — giving great attention to detail, very exact, and often hard to satisfy. Meticulous is the nearest synonym in the sense of careful, precise work. Inattentive is the opposite. Example: She kept fastidious records of every transaction.
• debilitating — causing severe weakness or loss of strength. Crippling has the same sense of serious, lasting disability. Critical means dangerous or at a crucial stage, so it is not a synonym here. Example: The fever was debilitating for the whole week.
• bilateral — involving two sides, such as two countries or two parties. Bipartisan means involving or agreed upon by two parties. Impartial means not favouring either side, so it does not describe joint action. Example: The two parties reached a bipartisan agreement on the budget.

When two options both look plausible, decide by the exact nuance of the sentence. Synonym questions in the exam usually test the core sense of a word, so a word that is only loosely related, such as a word from the same field, should be eliminated.

Advanced vocabulary meanings

Advanced vocabulary items test three things: the exact sense of a word, the part of speech and collocation it requires, and the difference between words that look or sound alike. The wrong options are usually real English words used in the wrong sense, so learn each word together with its usual partner, such as a preposition, a noun, or a passive form.

Figurative and idiomatic senses. Many words carry a meaning that is figurative rather than literal. A turncoat is a person who deserts one party, cause or group and changes allegiance to its rivals. The word has nothing to do with clothing, and it describes betrayal of a former side rather than general dishonesty. Top-notch is an adjective meaning of the highest standard or excellent in quality, and it is used for products, services and performances. Aplomb is a noun meaning calm self-confidence under pressure. It was borrowed from French, and a speaker who answers hostile questions without losing composure shows aplomb. Condign describes a punishment that is deserved and suited to the wrong committed, so it refers to a fitting penalty rather than a severe one in general. Brain drain is the emigration of skilled professionals in search of better opportunities abroad.

• Incommunicado — without any means of communicating with other people, often through deliberate isolation. It comes from Spanish and is frequently used of a prisoner held without contact.
• Gastronomy — the art and science of fine food and eating. It is not the study of digestion, which belongs to physiology or gastroenterology.
• Expatriate — a person who lives in a country other than the one of which he or she is a citizen. The prefix ex- means out of and the Latin patria means native land.
• Alibi — evidence that the accused was elsewhere when the offence was committed. Establishing an alibi is a defence that can lead to acquittal, while a rejected or false alibi cannot be the reason for an acquittal.
• Immolate and emulate — immolate means to sacrifice or kill, often by fire, and emulate means to try to equal or copy someone admired. Emulate suggests admiration, whereas immolate suggests sacrifice; simulate, meaning to imitate or feign, is a third and different word.
