Forming Complex Sentences with Subordinating Conjunctions

Complex sentences combine an independent clause with a dependent clause using a subordinating conjunction. The basic structure is: independent clause + subordinating conjunction + dependent clause.

  • He decided to go for a walk while the weather was nice.

  • We will go on a trip provided that everyone agrees.

Tips for correct usage:

  • Place the subordinating conjunction at the beginning of the dependent clause.

Common Mistakes and How to Avoid Them

Overusing Certain Subordinating Conjunctions

Overuse of specific conjunctions can make writing repetitive. Vary your use of subordinating conjunctions to keep your writing engaging.

Misplacing the Subordinating Conjunction in a Sentence

Ensure the subordinating conjunction is correctly placed to maintain sentence clarity. A misplaced conjunction can confuse the reader.

Mixing Up Subordinating Conjunctions with Coordinating Conjunctions

Subordinating conjunctions connect clauses with different levels of importance, while coordinating conjunctions connect clauses of equal importance. Ensure you use the correct type for your sentence structure.
