4.3 Parts of Speech in Depth: Articles, Prepositions & Determiners
Key Takeaways
- The NTS curriculum names eight parts of speech under B2 — conjunctions, nouns, pronouns, verbs, adverbs, adjectives, articles and prepositions — worth 10% of the verbal segment.
- Article choice follows countability and specificity: 'a/an' for a non-specific singular count noun, 'the' for a noun already identified, and zero article for generic plurals and uncountables.
- 'A' versus 'an' is decided by the opening sound, not the opening letter, so it is 'an hour' but 'a university'.
- Uncountable nouns take much, little and amount; countable plurals take many, few and number.
- Dependent prepositions are fixed by the governing word, so they must be learned as pairs such as capable of, insist on, and different from.
Parts of Speech in Depth: Articles, Prepositions & Determiners
The official NTS curriculum lists B2: Part of Speech at 10% of the verbal segment and spells out the eight categories it covers: conjunctions, nouns, pronouns, verb, adverb, adjectives, articles, and prepositions. Articles and prepositions are listed last but generate the most lost marks, because both are decided by rules that Urdu and Punjabi do not share with English. Urdu has no articles at all, and its postpositions do not map one-to-one onto English prepositions. These are therefore learned systems, not intuitions.
Articles: A Three-Way Decision
English forces a choice among a/an, the, and no article on every common noun. Two questions settle it.
Question 1 — Is the noun countable and singular? If yes, it must have a determiner; a bare singular count noun is ungrammatical. I bought book is always wrong.
Question 2 — Can the listener identify which one? If yes, use the. If no, use a/an.
| Situation | Article | Example |
|---|---|---|
| First mention, singular count | a / an | I sat a test in Lahore. |
| Second mention, now identified | the | The test lasted two hours. |
| Unique or shared referent | the | the sun, the Higher Education Commission, the Indus |
| Superlative or ordinal | the | the highest score, the first attempt |
| Generic plural | none | Candidates must bring original CNICs. |
| Uncountable, general | none | Preparation requires patience. |
A or An: Sound, Not Spelling
The rule is phonetic. Use an before a vowel sound and a before a consonant sound:
- an hour, an honest answer, an MBA, an NTS invigilator (the letters M and N open with vowel sounds: em, en)
- a university, a European candidate, a one-day workshop (these open with a y or w glide)
Zero Article With Institutions
He went to school means he attended as a student; He went to the school means he visited the building. The same contrast applies to hospital, college, university, prison, and court. NTS uses this pair regularly.
Determiners and Countability
Quantifying determiners split along the countable/uncountable line, and mixing them is a high-frequency error:
| Countable plural | Uncountable | Both |
|---|---|---|
| many, few, a few, fewer, number of | much, little, a little, less, amount of | some, any, a lot of, plenty of, most, all |
- Right: There were fewer candidates and less noise this year.
- Wrong: There were less candidates.
- Right: A large number of students applied; a large amount of paperwork followed.
A few / a little are positive (some, enough); few / little without a are negative (hardly any). He has a few friends at the centre is reassuring; He has few friends at the centre is not. That single article flips the meaning, and NTS builds items on it.
Prepositions: Three Working Families
Family 1 — Place
| Preposition | Sense | Example |
|---|---|---|
| in | enclosed space, large area | in the hall, in Karachi, in Punjab |
| on | surface, line, street | on the desk, on page 4, on Mall Road |
| at | precise point, address, event | at the gate, at 96 Street 4, at the test centre |
Family 2 — Time
| Preposition | Used with | Example |
|---|---|---|
| at | clock times, festivals | at 9:00 a.m., at Eid |
| on | days and dates | on Sunday, on 18 January |
| in | months, years, seasons, parts of day | in August, in 2026, in the morning |
Note the exception: at night, not in night.
Family 3 — Movement and Direction
to (destination), into (entry), onto (contact with a surface), from (origin), towards (direction without arrival), through (passage inside), across (surface traverse).
Dependent Prepositions: Fixed Pairs
The hardest preposition items are not about meaning at all. The preposition is fixed by the preceding word and simply has to be known:
| Adjective + prep | Verb + prep | Noun + prep |
|---|---|---|
| capable of, afraid of | insist on, rely on | need for, reason for |
| different from, absent from | consist of, approve of | solution to, key to |
| responsible for, famous for | object to, refer to | increase in, interest in |
| interested in, involved in | depend on, comment on | attitude towards |
| similar to, superior to | congratulate on, blame for | advantage over |
Common errors to memorise as pairs: discuss takes no preposition (discuss the syllabus, not discuss about); so do enter, marry, reach, resemble, emphasise and investigate. Conversely, listen, reply, apologise and belong always require one.
Pronoun Agreement and Case
A pronoun must match its antecedent in number and the sentence slot in case:
- Subject case after a linking verb: It was he who scored highest.
- Object case after a preposition: between you and me, never between you and I.
- Indefinite pronouns are singular: everyone, somebody, each, neither, either take singular verbs — Everyone has brought his or her roll number slip.
- Collective nouns take a singular verb when the group acts as one unit: The committee has announced its decision.
Exam habit: when a preposition and a compound object appear together, delete the other person and re-read. Between you and I becomes between I — audibly wrong, which exposes the error instantly.
