IELTS Writing

A subordinate clause is a group of words containing a subject and a verb, but it does not express a complete thought and cannot stand alone as a sentence. Instead, it depends on a main (independent) clause to give it meaning. Subordinate clauses are often introduced by subordinating conjunctions such as because, although, if, or when.

Importance in IELTS Writing

  • Grammatical Range and Accuracy: The IELTS Writing band descriptors emphasize the use of a variety of complex sentence forms. Subordinate clauses are a key feature of complex sentences, which can help candidates meet the criteria for higher band scores.
  • Clarity and Cohesion: Using subordinate clauses allows writers to show relationships between ideas, such as cause and effect, contrast, or condition. This can improve the clarity and logical flow of an essay or report.
  • Example: In the sentence "Although public transport is convenient, many people prefer to drive their own cars," the clause "Although public transport is convenient" is a subordinate clause. It cannot stand alone but adds important context to the main clause.
  • Common Errors: Candidates sometimes write incomplete sentences by using subordinate clauses alone. Ensuring that each subordinate clause is attached to a main clause helps avoid sentence fragments and improves writing quality.
