2.2 Dependent Prepositions, Idiomatic Expressions & Fixed Phrases
Key Takeaways
- Dependent prepositions are bound to specific adjectives, verbs, and nouns; checking the preposition immediately following a gap often eliminates three out of four choices instantly.
- Cambridge test writers frequently offer four verbs or adjectives with nearly identical semantic meanings, where only one is syntactically compatible with the trailing preposition.
- Fixed phrases and idiomatic expressions (e.g., 'at first glance', 'in the long run', 'take for granted') are invariable lexical blocks that resist synonym substitution.
- Scanning the immediate 'one-word window' adjacent to the gap is the single fastest tactical heuristic for solving dependent preposition questions.
2.2 Dependent Prepositions, Idiomatic Expressions & Fixed Phrases
Quick Answer: Dependent prepositions are prepositions governed strictly by a preceding adjective, verb, or noun (e.g., interested in, rely on, demand for). In Part 1, identifying the preposition that appears immediately after or before the gap is the single fastest way to solve a question. Even if all four options share the same general definition, only one will be syntactically compatible with the governing preposition.
The Mechanical Power of Dependent Prepositions
When Cambridge assessment specialists author Part 1 items, they routinely construct questions where the distinguishing factor is not vocabulary knowledge in isolation, but syntactic complementation.
Consider this sentence:
The success of the wildlife rehabilitation project _____ entirely on the continued commitment of local volunteers.
- A) trusts
- B) insists
- C) counts
- D) believes
All four verbs convey positive expectation, faith, or reliance. However:
- trust is transitive and takes a direct object without a preposition (trusts the volunteers).
- insist takes on, but demands an action or assertion (insists on helping), not a subject's state of existential reliance.
- believe takes in (believes in the volunteers).
- count governs the dependent preposition on to mean depend or rely (counts on the commitment).
Scanning just one word past the gap to notice the word on eliminates three options instantly, reducing decision time from forty seconds to five.

Practical Walkthroughs: Instant Elimination in Action
Walkthrough 1: The Verb-Preposition Filter
Exam Sentence: The local wildlife trust managed to (1) _____ the historic woodland from being cleared by property developers.
- A) prevent
- B) forbid
- C) avoid
- D) refuse
Step-by-Step Tactical Elimination:
- Inspect the forward co-text: Notice the structure directly following the gap:
the historic woodland(noun phrase object) +from being cleared(preposition from + passive gerund). - Test Option B (forbid): Forbid governs an object plus full infinitive (forbid developers to clear), never from.
- Test Option C (avoid): Avoid is strictly transitive and takes a direct gerund without an object intermediary (avoided being cleared), but cannot take an object followed by from.
- Test Option D (refuse): Refuse governs a full infinitive (refused to clear), never an object + from.
- Evaluate Option A (prevent): Prevent precisely governs the pattern
prevent + object + from + -ing(prevent the woodland from being cleared). Option A is correct.
