What is subcordinating clause

Dear Student,

A subordinate clause is a clause that cannot stand alone as a complete sentence. It, simply, complements a sentence’s main clause. It is also known as a dependent clause.

Example: Even though the pasta was covered in cheddar cheese, Rahul refused to eat it. Here,

Even though the pasta was covered in cheddar cheese - Subordinate clause
Rahul refused to eat it - Main clause
