Articles & Nouns

'Honest' begins with a silent 'h' — the vowel sound /ɒ/ follows, so use 'an'. 'Decade' begins with the consonant sound /d/, so use 'a'. The article rule is based entirely on the initial sound of the following word, never its spelling. 'An honest' is correct; 'a honest' is the classic CDS error.

'University' begins with the /j/ (y) consonant sound — not a vowel sound — so use 'a'. 'Unique' similarly begins with /j/. Both take 'a', not 'an'. The letter 'u' looks like a vowel, but the sound that follows is a consonant (y-sound), making this one of the most commonly tested traps in CDS Fill in the Blanks.

'One' begins with the /w/ consonant sound, so use 'a one-man army'. 'MBA' is read letter by letter as 'em-bee-ay' — it begins with the vowel sound /em/, so use 'an MBA'. Both words trap students into wrong choices: 'one' looks like a vowel, and 'M' looks like a consonant. Sound decides — not spelling.

'European' begins with the /j/ (y) consonant sound — 'yoo-roh-pee-an'. Therefore it takes 'a', not 'an'. 'Historic' begins with a clearly pronounced /h/, so 'a historic' is correct. 'Asian' begins with the vowel sound /eɪ/, so 'an Asian' is correct. The error is only in 'An European' — it should be 'A European'.

Mountain ranges always take 'the' — the Himalayas, the Andes, the Alps. However, individual peaks do not take 'the' — Mount Everest, not 'the Everest'. Oceans also require 'the' — the Pacific. Option A is wrong (the Everest → Mount Everest). Option B is wrong (the Pacific needed). Option D is wrong (the Andes needed).

All three blanks require 'the'. 'The sun' — unique celestial object, only one exists. 'The east' and 'the west' are specific, unique directions — always used with 'the'. Unique or one-of-a-kind objects and fixed directional references always take the definite article 'the'. This is a standard CDS Fill in the Blanks pattern.

'An most experienced' is wrong. Superlatives always take 'the' — 'the most experienced'. 'An' is used before vowel sounds for indefinite references, not before superlatives. The correct form is 'the most experienced nurse'. Options A, B, and C are all correct — 'the best' (superlative), 'the piano' (instrument), 'the chairman' (specific role) all correctly use 'the'.

'Accident' begins with the vowel sound /æ/, so use 'an accident'. 'Highway' is a specific, contextually known road being referred to — use 'the highway'. The rule: use 'an' before vowel sounds for first/non-specific mention, and 'the' when the noun is specific or contextually identified. 'An accident on the highway' is correct.

'Advice' is an uncountable noun — it has no plural form and cannot be preceded by 'a/an'. Saying 'an advice' or 'advices' is incorrect. The correct forms are: 'a piece of advice' or 'some advice'. 'Suggestion', 'report', and 'document' are all countable nouns and take 'a/an' and plural forms normally. Other common uncountable nouns: information, luggage, furniture, equipment.

'Information' is an uncountable noun — it has no plural form. 'Informations' is always wrong. The correct form is 'much information' or 'a great deal of information' or 'pieces of information'. Similarly, 'advice', 'furniture', 'luggage', 'equipment', and 'knowledge' are all uncountable and cannot be made plural. This pattern appears regularly in CDS Spotting Errors.

When a collective noun acts as a single unified body, it takes a singular verb and singular pronoun — 'The jury has reached its verdict.' Options A, B, and D treat the jury as individuals acting separately (debating, arguing, each) — which would use plural verbs. The key is context: unified action → singular; individual members acting separately → plural. CDS typically expects unified action with singular.

'Advice' is uncountable — it takes no article ('a' or 'an') and has no plural. 'Suggestions' is the correct plural of the countable noun 'suggestion'. So the correct form is: 'He gave me good advice and two suggestions about the route.' No article before 'advice'; the numeral 'two' requires the plural 'suggestions'. Option B with a dash (no article) is correct.

Deserts take 'the' — the Sahara, the Gobi, the Atacama. Option A is wrong: 'the Taj Mahal' is required (specific monument). Option C is wrong: individual peaks are 'Mount Everest' without 'the'. Option D is wrong: titles directly before proper names do not take 'the' — 'Captain Sharma', not 'the Captain Sharma'. Only B is correct.

'Cattle' is always plural — it never takes 'a' or 'an', and it never takes a singular verb. 'A cattle' is doubly wrong. The correct form is simply 'Cattle were grazing…'. Similarly, 'people', 'police', and 'clergy' are always plural and never take 'a/an'. 'Cattle' has no singular form in standard English — one animal is 'a cow', 'a bull', or 'a calf'.

Abstract nouns used in a general, universal sense take no article — 'Courage is the foundation of leadership.' Option A is wrong: 'honesty' used as a universal principle takes no article — 'Honesty is the best policy.' Option B is wrong: 'life' used generally takes no article — 'Life is full of surprises.' Option D is wrong: uncountable abstract nouns like 'courage' cannot take 'a/an'. Only C correctly uses the zero article.

'The Ganga' — rivers always take 'the'. 'A sacred river' — first mention, non-specific, countable → 'a'. 'Northern India' — general geographical areas without a boundary or institution take no article. 'The northern India' would be wrong. So: 'The Ganga is a sacred river that flows through northern India.' Option B (with a dash for no article) is correct.

Officer, mission, platoon, and document are all countable nouns — they have singular and plural forms and can be preceded by 'a/an'. Option A contains uncountable nouns (furniture, equipment, luggage, baggage). Option C contains uncountable nouns (knowledge, information, advice, news). Option D contains abstract uncountable nouns (courage, honesty, patience, wisdom). Only option B is a set of countable nouns.

'The honest man' implies a specific, already-identified man. But the sentence introduces him for the first time with no prior context — so the indefinite article is needed: 'He is an honest man'. Note: 'honest' begins with silent 'h' → vowel sound → 'an'. 'The' is used when both speaker and listener know exactly which person or thing is meant — that condition is not met here.

Musical instruments take 'the' when referring to playing them — 'the violin', 'the piano', 'the guitar'. Languages take no article — 'speaks French', not 'the French'. Option A is wrong ('a violin' and 'the French'). Option C is wrong (no article before 'violin'). Option D is wrong ('the French'). Only option B is fully correct.

'Eye' begins with the vowel sound /aɪ/ — use 'an'. 'Ability' begins with the vowel sound /ə/ — use 'an'. Both nouns are first mentions with no prior context, so the indefinite article is needed. 'A eye' and 'a ability' (option C) are wrong because both words begin with vowel sounds, making 'a' incorrect for both. 'The eye … the ability' (option A) are wrong because neither noun is previously identified or specific. 'A … an' (option D) is wrong because 'eye' begins with a vowel sound and needs 'an'. Only 'an … an' is correct.
