Adverbial subordinate clauses, adjectival subordinate clauses, and nominal subordinate clauses.
This is called a compound complex sentence. The main clauses are usually connected by a conjunction. The subordinate clause is connected to a main clause by an adverb.

the subordinate noun comes before the verb in the main clauses
One false statement about subordinate clauses is that they always function as independent sentences on their own. Another false statement is that they are always placed at the beginning of a sentence. Subordinate clauses can also come after the main clause in a sentence.

Some examples of subordinate clauses include adverbial clauses (e.g. "because she was tired"), relative clauses (e.g. "who lives next door"), and noun clauses (e.g. "what you said"). Subordinate clauses cannot stand alone as complete sentences because they rely on the main clause for context and meaning.
No, a coordinating conjunction introduces an independent clause. Subordinate clauses are introduced by subordinating conjunctions.
These are called compound clauses. An example: [I went to the shop] and [I bought a loaf of bread].
No, "fortunately" is an adverb, not a subordinate conjunction. It is used to express a positive outcome or circumstance. Subordinate conjunctions connect dependent clauses to independent clauses in a sentence.
A subordinate clause adds extra information to a main clause, providing a deeper understanding or context to the main idea. It typically cannot stand alone as a complete sentence and relies on the main clause for full meaning. Subordinate clauses are often introduced by subordinating conjunctions such as "because," "although," or "if."
A preposition is a part of speech used to show the relationship between a noun or pronoun and other words in a sentence. It typically indicates location, direction, time, or the relationship between nouns or pronouns.
