Writing: Complex Sentences Subordination
Complex sentences subordination is the B2 writing skill that produces sophisticated multi-clause sentences. The technique uses subordinating conjunctions to signal relationships: because, since, as (reason); although, even though, while, whereas (contrast); if, unless, provided that (condition); when, before, after, until, as soon as (time); so that, in order that (purpose). Learners build sentence-variety fluency essential for B2-level writing.
This worksheet builds B2 writing fluency with subordination techniques.

Common challenges: Subordinator-meaning precision at B2 — because and since both give reasons, but since often combines reason and time. Comma placement: subordinate-first clauses take a comma (Although it rained, we went out); main-first clauses don’t (We went out although it rained). Variety: avoiding repeated because and although by rotating equivalents.
