Civil Service Exam (Subprofessional) Verbal Ability — Vocabulary — Modals, Affixes, Context Clues & Word UsageFlash Cards

What is the difference between CAN and MAY when expressing permission?

CAN is commonly used to ask for permission in informal situations, while MAY is used in formal situations. Example: 'Can I use your pen?' (informal) vs. 'May I be excused?' (formal). Both are acceptable, but MAY shows more politeness and formality.

Define COULD HAVE and provide an example of its usage.

COULD HAVE expresses past ability or opportunity that was not used or realized. It suggests something was possible but didn't happen. Example: 'He could have been a great doctor, but he chose teaching instead.' This shows he had the ability but made a different choice.

What does the prefix 'anti-' mean? Give three examples.

Anti- means 'against' or 'opposite of.' Examples: antidepressant (against depression), anticlimax (opposite of climax), antibacterial (against bacteria). This prefix is commonly used in medical, scientific, and general vocabulary.

Identify the context clue type: 'The acrid smell of burning tires quickly made our eyes water.'

This is an INFERENCE context clue. We can deduce that 'acrid' means an unpleasant, sharp smell because: 1) burning tires have a harsh odor, 2) it made eyes water, 3) our knowledge tells us such smells are irritating. The meaning isn't directly stated but can be reasoned out.

Distinguish between SHOULD and MUST in terms of obligation strength.

MUST expresses strong obligation or necessity - something is required. SHOULD expresses mild obligation, advice, or expectation - something is recommended but not mandatory. Example: 'You must stop at red lights' (law) vs. 'You should eat healthy food' (advice).

What does the suffix '-ous' mean and provide examples?

The suffix '-ous' means 'possessing the qualities of' or 'full of.' Examples: porous (full of pores), igneous (relating to fire/heat), ambitious (full of ambition). It typically forms adjectives from nouns, describing characteristics or qualities.

Explain SYNONYM context clues with an example.

Synonym context clues provide words with similar meaning nearby. Example: 'He committed a heinous crime from which he will never be able to recover.' The phrase 'never be able to recover' suggests heinous means extremely serious or wicked, giving us the meaning through similar context.

What is the correct usage of AFFECT vs EFFECT?

AFFECT is a verb meaning 'to influence' - 'The rain will affect our picnic.' EFFECT is a noun meaning 'result' - 'The effect of rain was a cancelled picnic.' Memory trick: Affect = Action (both start with A), Effect = End result (both start with E).

When do we use MIGHT vs MAY for possibility?

MAY indicates higher probability or serious possibility: 'It may rain today' (likely). MIGHT indicates lower probability or remote possibility: 'It might rain next week' (less certain). MAY suggests more immediate or serious possibility than MIGHT.

What does the prefix 'dis-' mean and how does it change word meaning?

Dis- means 'not' or 'opposite of,' creating negative meanings. Examples: dislike (not like), disappear (opposite of appear), disconnect (not connected). It reverses or negates the original word's meaning, often creating antonyms.

Identify the context clue: 'Some men are garrulous, but most of them hardly talk at all.'

This is an ANTONYM context clue. The word 'but' signals contrast, showing garrulous means the opposite of 'hardly talk at all.' Therefore, garrulous means talkative or chatty. The signal word 'but' indicates opposite meanings.

Explain the difference between SHALL and WILL in questions.

Use SHALL with I/we for offers, suggestions, and advice: 'Shall we have dinner?' Use WILL with other pronouns for requests and predictions: 'Will you help me?' WILL is also used for future predictions: 'Will it rain tomorrow?'

What does the suffix '-ment' indicate and provide examples?

The suffix '-ment' indicates 'action or process' and forms nouns. Examples: achievement (act of achieving), movement (act of moving), development (process of developing). It typically converts verbs into nouns representing the action or result.

Distinguish between AMOUNT and NUMBER in usage.

AMOUNT refers to uncountable quantities (bulk): 'amount of water, money, time.' NUMBER refers to countable units: 'number of students, books, cars.' Rule: If you can count individual items, use NUMBER; if it's a mass or bulk quantity, use AMOUNT.

What is a DEFINITION/DESCRIPTION context clue? Give an example.

Definition context clues explicitly define or describe the unfamiliar word within the sentence. Example: 'Playing volleyball exacerbated his ankle injury. It aches a lot more than it did.' The second sentence defines exacerbated as 'made worse.' Look for commas, dashes, or explanatory phrases.

Compare OUGHT TO and SHOULD in terms of formality and usage.

Both express expectation or advice, but OUGHT TO is more formal than SHOULD. Examples: 'You should study harder' (common) vs. 'You ought to respect your elders' (formal). OUGHT TO suggests stronger moral obligation, while SHOULD is more general advice.

What does the prefix 'pre-' mean and how is it used?

Pre- means 'before' in time, place, or order. Examples: prescribe (write before), preview (see before), prehistoric (before recorded history). It indicates something that comes earlier or happens in advance of something else.

Explain the correct usage of FEWER vs LESS.

FEWER is used with countable items: 'fewer people, books, cars.' LESS is used with uncountable quantities: 'less water, time, money.' Memory trick: If you can count individual items, use FEWER; if it's a mass quantity, use LESS.

What is the function of WOULD in giving advice?

WOULD is used to give hypothetical advice, often with 'If I were you.' Examples: 'If I were you, I would study abroad' or 'I wouldn't try that.' It suggests what the speaker would do in the listener's situation, making advice less direct and more polite.

What does the suffix '-ly' typically create and provide examples?

The suffix '-ly' typically creates adverbs from adjectives, describing 'how' something is done. Examples: quickly (quick + ly), carefully (careful + ly), happily (happy becomes happily). It transforms descriptive words into words that modify actions or verbs.
