Subordinating conjunctions join a dependent clause to an independent clause, showing relationships like cause, time, condition, and contrast. They help make writing more precise and coherent.
Key Conjunctions
Some common subordinating conjunctions are because, although, if, when, since, while, and unless. Each one signals a particular kind of relationship between the clauses.
Because
Use because to give a reason for something. The clause with because explains why the action in the main clause happens.
Ella se quedó en casa porque se sentía enferma.
Although
Use although to show contrast. It introduces a surprising or opposing idea relative to the main clause.
If
Use if to introduce a condition. The main clause depends on whether the condition in the if clause is met.
When
Use when to indicate time. It connects an action to a specific moment or period.
Since
Use since to show cause or time. It can explain a reason or refer to a point in time from which something has happened.
While
Use while to show simultaneous actions or contrast. It can introduce two things happening at the same time or highlight a difference.
Unless
Use unless to set a negative condition. It means "except if" and specifies when the main clause will not happen.
Summary
Subordinating conjunctions signal important relationships between ideas and make sentences more nuanced. Practice using different ones to clearly show cause, time, condition, and contrast.
