Subordinating conjunctions in Spanish are words used to connect a main clause with a subordinate (dependent) clause. They help to express reasons, conditions, purposes, time, and more.
Use these conjunctions in Spanish to join two clauses when one depends on the other. For example, to explain a reason (because), a condition (if), or a purpose (so that).
