Why This Matters

A preposition question looks trivial and is worth a mark: "comply ___ the rules" has exactly one correct answer, and it is correct because it is the fixed pairing, not because it follows a rule of logic. The same is true of "effect" against "affect", "principal" against "principle", and the handful of confusable word pairs the paper reuses every cycle.

This is the most efficiently learned material in the whole verbal section: a closed list of roughly sixty items, each learned with one sentence. Two hours of study here typically converts to three or four marks, and those marks cannot be lost again by a bad day.

A Simple Model

Prepositions are not chosen by meaning — they are chosen by memory of the pairing. So the study method is not reasoning, it is a list rehearsed with a sentence each:

verb + fixed preposition  ·  adjective + fixed preposition  ·  idiom as an unbreakable unit

Two habits make the list stick. First, always store the pair, never the preposition alone: "depend on", not "on". Second, store a real sentence with it: "the result depends on the sample size". A remembered sentence survives stress; a remembered list does not.

Read the pair aloud in a sentence. Confusion between effect and affect usually disappears the moment the word has to carry a verb's work: "the policy will ___ prices" can only take affect.
Do not reason from meaning. Many candidates argue that "comply to the rules" should be right because rules are something you move towards. The exam does not grade arguments; it grades the fixed pairing. When in doubt, recall the sentence you memorised.

Worked Examples

1. All staff must comply ___ the new safety rules.

Comply pairs with with: comply with the rules. Offering "to" comes from reasoning that you comply to an authority — but comply takes with whoever or whatever you obey.

2. The delay had no ___ on the final schedule.

Here the blank needs a noun after "had no", so it is effect. "Affect" is the verb form, and "effected" would mean brought about, which changes the meaning.

3. She is senior ___ the other officers.

Senior takes to, never "than": she is senior to the other officers. The "than" version is the classic trap because the sentence means a comparison.

4. The plan was abandoned ___ account of the strike.

The idiom is on account of. The alternatives "in account of" and "by account of" are inventions that look plausible under pressure.

Try It

All staff must comply ___ the new safety rules.

She is not afraid ___ criticism.

The new policy had no ___ on prices.

The meeting was postponed ___ account of the strike.

Check Your Understanding

Without looking back: which preposition follows "consist", "depend" and "responsible"?

The answer: consist of, depend on, responsible for.

We say depend , consist and responsible . The noun form of affect is .

Apply It

Correct the preposition or word error in each sentence: (1) "The committee insisted for a written report." (2) "His answer was different than mine." (3) "Neither of the options had any affect on the result." (4) "She is capable to handling the project alone."

Show the reasoning

(1) Insist takes on: insisted on a written report.

(2) In formal writing, different pairs with from: different from mine. "Different than" appears in informal use, especially before clauses, and the exam prefers from.

(3) The noun is needed, so effect: no effect on the result.

(4) Capable pairs with of, and of takes the -ing form: capable of handling the project alone.

Notice the pattern in all four: each error is a fixed pairing replaced by a plausible-sounding alternative. That is why this material is learned as a list of pairs and sentences rather than as a set of rules.

Connect

Words, relationships, grammar and fixed pairs are now in place. The next lesson is the largest single verbal block on the paper and the one where technique beats vocabulary: reading comprehension under a clock.
