Topic Explanation and Use
Core idea
A longer sentence is only better if the reader can still follow it easily.
Clause-building means combining one clear main idea with supporting clauses without losing control of the sentence. A strong complex sentence still feels easy to follow on the first read.
Use extra clauses to show time, reason, condition, contrast, or added detail. If the link between the clauses is weak, split the sentence and rebuild it.
At B2 level, build one correct base sentence first, then add detail without breaking grammar control.
Use it here
- Start with a complete main clause before you add support.
- Make the link between clauses visible with punctuation or a clear linker.
- Cut extra material if the sentence becomes harder to scan than the meaning is worth.
Watch it work
Remember this
- Write one complete main clause first.
- Add the support clause only after the main clause is stable.
- Show the relationship between clauses clearly with punctuation or a linker.
- Check that each clause is attached to the correct part of the sentence.
- Split the sentence if the reader has to work too hard to follow it.
