1. Subordinating Conjunctions and Complex Sentences

2. The purpose
The purpose of a subordinating conjunction is to establish a relationship between the independent and dependent clauses.
TO CREATE COMPLEX SENTENCES =
DEPENDENT CLAUSE + INDEPENDENT CLAUSE

3. Just a reminder… An independent clause is a complete sentence.
Example: Johnny likes waffles.
A dependent clause is not a complete sentence.
Example: Although Johnny likes waffles
See? There has to be an independent clause to make “Although Johnny likes waffles” a complete sentence.

4. The Lineup
after although as as if as long as as though because before even if even though
if if only in order that now that once rather than since so that than that
though till unless until when whenever where whereas wherever while

5. Example Sentences
Although I ate breakfast, I was hungry at 10:00. I am going to write the paper since you did the research Even though you lost the book, I will loan you another one. Because you ate the last muffin, you have to buy a new batch.

6. Note
If the sentence begins with the dependent clause, such as: Although I ate breakfast, I was hungry at 10:00.
a comma will follow .

7. Why should I do this?
The sentences are complex and boost scores when used correctly. Also, English teachers love them and so do college professors. HOWEVER! Do not overdo it! 1-2 per paragraph is plenty!
