German Conjunctions: Coordinating vs Subordinating and Why Word Order Changes

If you've ever searched 'why does the verb go to the end in German', the answer is usually: a subordinating conjunction. German conjunctions come in two types that work completely differently. Coordinating conjunctions join two main clauses and don't change word order. Subordinating conjunctions introduce a dependent clause and send the verb to the end. Getting this right is the difference between A2 German (simple sentences) and B1 German (complex, natural sentences). This guide covers every important conjunction with example sentences.

Coordinating conjunctions: no word order change

These connect two main clauses and the second clause keeps normal word order (subject-verb): und (and), aber (but), oder (or), denn (because/for), sondern (but rather), doch (yet/but). Ich lerne Deutsch und ich schaue deutsche Serien — I learn German and I watch German series. Ich möchte fließend Deutsch sprechen, aber es ist schwierig — I want to speak German fluently, but it's difficult. Er kommt nicht, denn er ist krank — He's not coming because he's ill. Note: 'denn' does NOT send the verb to the end — it's coordinating. This is the most common mistake learners make searching 'weil vs denn German difference'.

Subordinating conjunctions: verb goes to the end

These introduce a dependent clause and the conjugated verb moves to the very end: weil (because), dass (that), wenn (when/if), ob (whether), obwohl (although), während (while), bevor (before), nachdem (after), als (when — single past event), seit (since), damit (so that), falls (in case), bis (until). Ich schaue deutsche Serien, weil es mir hilft — I watch German series because it helps me. Er weiß, dass Deutsch schwer ist — He knows that German is hard. The verb goes to the very end of the clause. With modal verbs: ..., weil er Deutsch lernen muss (because he must learn German).

Weil vs denn: why learners always confuse these

Both mean 'because' but work differently. Weil is subordinating — verb goes to the end: Ich lerne Deutsch, weil ich in Deutschland arbeiten will. Denn is coordinating — normal word order: Ich lerne Deutsch, denn ich will in Deutschland arbeiten. In spoken German, weil is far more common and natives increasingly use weil with normal word order informally (Weil ich will in Deutschland arbeiten) — this is grammatically incorrect but widespread in casual speech. For Goethe exams and formal writing, always use weil + verb-final. Understanding both helps you follow real German conversations where informal weil appears constantly.

Conjunctions in real German dialogue

Watch any German TV show for five minutes and you'll hear weil, dass, wenn, und, aber, oder constantly. These conjunctions are the connective tissue of every sentence in the German language. Learners who read German subtitles while watching notice patterns unconsciously — after dozens of hours, weil + verb-at-end becomes automatic. German learners using tools like Butterfluent to watch German video content with live subtitles naturally absorb conjunction patterns far faster than those who only study grammar exercises. The key to German fluency is combining grammar understanding with massive exposure to real German speech.
