Task 7: Describing a Relationship With a Preposition
Write sentences that use of, in, for, by, and through to build a real relationship between two ideas — producing the exact connections Lesson 7 teaches you to read as an author's logic, not a word to translate.
Learning Objectives
By the end of this task, you should be able to:
- Write one sentence using 'of' to show belonging or a part-whole relationship
- Write one sentence using 'by' correctly in a passive-voice sentence to name the agent
- Write one sentence using a fixed verb+preposition or adjective+preposition pair
Introduction
Lesson 7 taught you to read a preposition as an arrow connecting two ideas, rather than a single word with a fixed Bangla translation. Writing with that same awareness means choosing the preposition that builds the exact relationship you mean — not just the one that sounds close.
Choosing the Right Arrow
Core Concept
of connects a whole to a part or an owner: "the opinions of the team." by names who or what performs a passive action: "the report was written by the manager." Many verbs and adjectives are fixed to one particular preposition, and swapping it can flip the meaning: "the delay resulted in a loss" (delay caused the loss) versus "the loss resulted from a delay" (delay is the cause, stated after the result).
Your Turn
Your Turn
Write four sentences about your work: one using of to show a part-whole or belonging relationship, one passive sentence using by to name who did the action, and two more using fixed pairs from this list: depend on, responsible for, interested in, result in, result from.

Self-Check
Self-Check
- Does your "of" sentence genuinely show belonging or a part-whole relationship, not just proximity?
- In your passive sentence, does "by" correctly name who or what performed the action?
- Did you use at least two fixed verb/adjective + preposition pairs correctly?
