Subordinating conjunctions link a dependent clause to a main clause and often signal the type of relationship between ideas, such as time, cause, or condition.
Key Conjunctions
Key subordinating conjunctions include porque (because), aunque (although), si (if), and cuando (when), each serving a specific function to connect ideas.
Porque
Use porque to introduce a clause that gives a clear reason for something, linking cause and effect in a straightforward way.
I am not going out today because there is a lot of wind.
Aunque
Use aunque to introduce a concession or surprising fact, showing that one idea does not prevent another from happening.
Si
Use si to introduce a condition; the clause that follows determines whether the main clause can occur.
Cuando
Use cuando to introduce a time clause, indicating when something happens relative to another event.
More Conjunctions
Other subordinating conjunctions include mientras (while), para que (so that), desde que (since), and antes de que (before), each adding nuance to time, purpose, cause, or condition.
Summary
Subordinating conjunctions consistently link dependent clauses to main clauses and signal relationships like time, cause, condition, or concession; mastering them helps you organize complex ideas clearly.
