Topic 2: Main and Subordinate Clauses (Introduction)
A main clause can stand alone as a sentence, while a subordinate clause depends on the main clause to make complete sense.
Core concept
A main (independent) clause has a subject and verb and expresses a complete thought, like 'She went to school.'
How it works
A subordinate (dependent) clause also has a subject and verb but cannot stand alone, like 'because it was raining.'
Why it matters
Combining a main clause and subordinate clause creates a complex sentence, like 'She stayed home because it was raining.'
Key detail
Understanding clauses helps us write more varied and sophisticated sentences, improving our overall writing style.
