Prepositions and Articles: Small Words, Big Points in the CSE

The English part of Verbal Ability tests correct usage, and two groups of very short words cause a surprising number of lost points: prepositions (in, on, at, for, with) and articles (a, an, the). Filipino uses sa for many of the meanings English splits across several prepositions, so learners who translate directly often choose the wrong one. This guide gives you the rules that settle most questions.

Part 1: Prepositions of time

Think of a funnel, from large to small:

Use	For	Examples
in	months, years, seasons, long periods, parts of the day	in March, in 2027, in the rainy season, in the morning
on	days and dates	on Monday, on 14 March 2027, on Independence Day
at	exact times and points	at 9:00 a.m., at noon, at night, at the end of the month

Two related words often appear in error-recognition items:

• for + a length of time: absent for three days, worked here for five years.
• since + a starting point: worked here since 2020 (usually with the present perfect: has worked).
• until + the end point: postponed until further notice.

Part 2: Prepositions of place

• at a point or address: at the counter, at the city hall.
• in an enclosed space or area: in the office, in Quezon City, in the drawer.
• on a surface, a floor or a line: on the desk, on the third floor, on EDSA.

Movement uses into (from outside to inside: walked into the room) and onto. In describes position, into describes movement.

Part 3: Fixed pairs you should memorise

Many verbs and adjectives always take the same preposition. These appear often in formal and office writing:

Correct	Common error
comply with	comply to
responsible for (a task) / to (a person)	responsible of
insist on (+ -ing)	insist to
different from	different with
good at	good in (for skills)
absent from	absent in
depend / rely on	depend to
interested in	interested on
capable of	capable to
prefer A to B	prefer A than B
addressed to	addressed for

Between or among? Use between for two and among for three or more: divided among the four members. Between is still correct for clearly separate items, as in an agreement between the three agencies, but in exam items with a group, among is usually expected.

Part 4: A or an

The choice depends on the sound that follows, not the letter.

• an before a vowel sound: an hour, an honest employee, an MBA, an NGO (M and N are pronounced “em” and “en”).
• a before a consonant sound: a university, a one-time fee, a European country (“yoo” and “wun” begin with consonant sounds).

Say the word aloud in your head before you choose.

Part 5: The or no article

Use the:

• when the listener knows which one you mean: Please file the report you finished yesterday.
• with superlatives and ordinals: the best report, the first applicant.
• with plural country names or names with republic, kingdom or states: the Philippines, the United States, the Republic of Korea.
• with names of oceans, seas, rivers and island groups: the Pacific Ocean, the Pasig River, the Visayas.

Use no article:

• with most singular country, city and street names: Japan, Manila, Roxas Boulevard.
• with sports and most meals: plays volleyball, after lunch.
• with abstract and uncountable nouns used in a general sense: Honesty is the best policy. Patience is needed.
• with plural nouns used in a general sense: Applicants must bring two IDs.

Compare: Honesty is required (general) and The honesty of the witness was questioned (a specific person’s honesty).

How these appear in the exam

1. Fill in the blank: “All applicants must comply ___ the requirements.” The answer is with.
2. Error recognition: “The new guidelines are different (A) with the old ones (B) and take effect (C) on 1 July (D).” The error is A: it should be from.
3. Article choice: “She is ___ honest employee.” The answer is an, because the h is silent.

A short practice routine

• Each day, read one short government notice or news item and underline every preposition. Ask why each one is used.
• Keep a list of fixed pairs you get wrong and review it with the self-testing method from our active recall guide.
• Practise with our prepositions and articles questions and the error recognition set, where these mistakes are often hidden.
