There isn't a difference between a subordinate clause and a subordinate clause.
Yes, a comma is generally needed when a subordinate clause begins with a subordinate conjunction. The comma is used to separate the subordinate clause from the main clause.
"After the bridge collapsed" is the subordinate clause. It begins with "after", a subordinate conjunction, and it cannot stand alone as a sentence. A subordinate clause is also called a dependent clause.
The subordinate clause of the sentence is -- Although the ostrich is a bird
The sentence type that includes both a subordinate clause and an independent clause would be a complex sentence. You would need to insert a conjunction to separate the two clauses for the sentence to be grammatically correct.
A subordinating conjunction begins a subordinate clause. It connects the subordinate clause to the main clause and shows the relationship between the two. Examples of subordinating conjunctions include "although," "because," and "if."
Although there are many subordinate conjunctions, the most common are "and", "but", and "or". A subordinate conjunction connects a subordinate clause (a clause that cannot stand alone as a sentence) to a main clause (a complete sentence).
That is an independent clause. It would be a subordinate clause if you said, "I would like to know who...."
Correct way: Joe finished his homework before going to bed. (subordinate clause: before going to bed) Incorrect way: Joe finished his homework going to bed. (incorrect placing of the subordinate clause)
Subordinate clauseA subordinate (or dependent) clause is a clause that needs another clause. Unlike independent clauses it cannot stand alone. The word because is usually a good indicator of a subordinate clause.
If you have the subordinate clause before the main clause, you write a comma. However, the rules are a bit different for relative pronouns connecting main and subordinate clause.
