Subordinate clauses, or oraciones subordinadas in Spanish, are an essential part of mastering the language. They allow you to express complex ideas by connecting a main clause with a dependent clause. In simpler terms, a subordinate clause cannot stand alone as a complete sentence; it relies on the main clause to give it meaning. Whether you’re describing a condition, providing a reason, or expressing time, subordinate clauses are your go-to tool for adding depth and nuance to your Spanish conversations and writing.

In this blog post, we’ll explore everything you need to know about subordinate clauses in Spanish, including common expressions, conjugation rules, irregular verbs, and practical examples. By the end, you’ll be able to use subordinate clauses confidently in your daily Spanish communication.

   • Example: Los niños que juegan son felices. (The children who play are happy.)
