Thekey differencebetween main clause and subordinate clause is that themain clause expresses a complete thought whereas the subordinate clause (or dependent clause) doesn’t express a complete thought.
A clause is a group of words that contain asubject和predicate. Some clauses have the ability to express a complete meaning whereas some don’t. We can divide clauses into two categories according to this ability to express a complete thought: main clause or subordinate clause. Since main clause can convey a complete thought, it can stand independently. However, subordinate clause is dependent on the main clause since it cannot express a complete thought.

什么是主要条款？
A clause is a group of words that contain a subject and a predicate and can stand alone as an independent sentence. Let’s look at the following example:
He wanted to go to Francebecause his mother was born there.
The underlined clause in the above sentence has a subject and a predicate. It also gives a complete meaning and can stand as an independent sentence. Therefore, it is a main clause.
Every sentence has at least one main clause. Some sentences can have two main clauses. We call such sentences compound sentences. The two main clauses in a compound sentence are combined with acoordinating conjunction.

She loved her husband， 但他与另一个女人有染.
Finish your dinnerbefore the food gets cold.
We can’t help youunless you tell us your problem.
While I was driving,I noticed a huge poster in their front yard.
我丢了钻石项链，这很昂贵。
What is Subordinate Clause?
A subordinate clause, also known as adependent clause, is a clause that doesn’t convey a complete thought. A subordinate clause will also contain a subject and a predicate, just like a main clause. However, a subordinate clause always begins with a subordinate conjunction or a relative pronoun and gives additional information about the sentences.
Let’s look at some examples of subordinate clauses.
我会买房子when I have saved enough money.
He bought her a romance novelalthough she prefers thrillers.
百合，她生活在二十猫, doesn’t like strangers.
Whoever told you thatwas lying.
即使我告诉TH真理, the police didn’t believe me.
As you can see from the above examples, subordinate clauses can occur anywhere in the sentence.
What is the Difference Between Main Clause and Subordinate Clause?
A main clause can express a complete thought whereas a subordinate clause cannot express a complete thought. This is the key difference between main clause and subordinate clause. Since the main clause can convey a complete thought, it can stand independently. However, subordinate clause is dependent on the main clause since it cannot express a complete thought. Thus, a subordinate clause cannot stand alone as an independent clause.
The below infographic presents the difference between main clause and subordinate clause in tabular form.
概括– Main Clause vs Subordinate Clause
Main clause and subordinate clause are the two main categories of clauses. A main clause can convey a complete meaning; thus, it can stand alone as an independent sentence. However, a subordinate clause always depends on the main clause as it cannot convey a complete thought. This is the basic difference between main clause and subordinate clause.
