One of the defining milestones in moving from beginner (A2) to intermediate/advanced German (B1–C1) is mastering complex sentence structures (Satzverbindungen).
In simple main clauses (Hauptsätze), German follows the strict rule: The conjugated verb is ALWAYS in Position 2.
However, as soon as you connect clauses using conjunctions (Konnektoren), the conjugated verb can stay in Position 2, move to Position 1, or get pushed all the way to the very end of the sentence!
In this definitive guide, you will master the 4 distinct groups of German connectors, learn their exact word-order rules, discover subtle nuances (weil vs. da vs. denn), and conquer two-part connectors.
1. Group 1: Subordinating Conjunctions (Verb to the End!)
Subordinating conjunctions introduce dependent clauses (Nebensätze). They force the conjugated verb to jump to the VERY END of the clause.
The Word Order Formula:
[Main Clause] + , + [Subordinating Connector] + [Subject] + [Other Elements] + [CONJUGATED VERB]
Example: Ich bleibe zu Hause, WEIL das Wetter schlecht IST.
└── Main Clause ───┘ │ └── Subject ┘ └── Rest ──┘ └── Verb at End ┘
└── Connector ┘
Essential Subordinating Connectors List:
| Connector | Meaning | Nuance / Notes | Example Sentence |
|---|---|---|---|
| Weil | Because | Gives direct cause/reason | Ich lerne Deutsch, weil ich in Berlin wohne. |
| Dass | That | Follows verbs of knowing/thinking | Er weiß, dass du heute kommst. |
| Obwohl | Although / Even though | Concession (contrast to expectation) | Sie läuft, obwohl sie müde ist. |
| Da | Since / As | Used when cause is already known | Da es regnet, bleiben wir drinnen. |
| Wenn | If / Whenever | Conditional or recurring events | Ruf mich an, wenn du Zeit hast. |
| Als | When | Single specific past event | Als ich ein Kind war, wohnte ich in Köln. |
| Damit | So that | Expresses purpose (different subjects) | Ich erkläre es, damit du es verstehst. |
| Bevor | Before | Time sequence | Wasche die Hände, bevor du isst. |
2. Group 2: Coordinating Conjunctions (ADUSO — Position 0)
Coordinating conjunctions connect two equal main clauses (Hauptsatz + Hauptsatz).
The Golden Rule: ADUSO connectors occupy POSITION 0! They do NOT affect word order at all. The conjugated verb remains in Position 2.
The ADUSO Mnemonic:
- Aber (but)
- Denn (because – formal/written)
- Und (and)
- Sondern (but rather – used after a negative nicht/kein)
- Oder (or)
The Word Order Formula:
[Main Clause] + , + [ADUSO (Pos 0)] + [Subject (Pos 1)] + [CONJUGATED VERB (Pos 2)]
Examples:
- Ich möchte kommen, aber ich habe keine Zeit. (Pos 0: aber, Pos 1: ich, Pos 2: habe).
- Er isst keinen Fisch, sondern er isst Fleisch. (He doesn’t eat fish, but rather meat.)
- Ich esse Suppe, denn ich bin krank. (I eat soup because I am sick.)
3. Group 3: Adverbial Connectors (Inversion — Position 1)
Adverbial connectors act as adverbs occupying POSITION 1 in the second clause. Because the conjugated verb MUST remain in Position 2, the verb comes IMMEDIATELY AFTER the connector (Inversion of subject and verb)!
The Word Order Formula:
[Main Clause] + ; + [Adverbial Connector (Pos 1)] + [CONJUGATED VERB (Pos 2)] + [Subject (Pos 3)]
Key Adverbial Connectors:
| Connector | Meaning | Example Sentence |
|---|---|---|
| Deshalb / Deswegen / Darum | Therefore / That’s why | Es regnet; deshalb bleibe ich zu Hause. |
| Trotzdem | Nevertheless / Despite that | Er war krank; trotzdem ging er zur Arbeit. |
| Außerdem | Furthermore / In addition | Das Haus ist schön; außerdem ist es günstig. |
| Sonst | Otherwise | Beeil dich, sonst verpassen wir den Zug! |
4. Group 4: Two-Part / Correlative Connectors (Doppelkonnektoren)
At the B2–C1 level, using two-part connectors allows you to express sophisticated logical relationships:
1. Sowohl … als auch (Both … as well as)
- Sie spricht sowohl Deutsch als auch Spanisch. (She speaks both German and Spanish.)
2. Weder … noch (Neither … nor)
- Er hat weder Zeit noch Geld. (He has neither time nor money.)
3. Nicht nur … sondern auch (Not only … but also)
- Er ist nicht nur intelligent, sondern sieht auch gut aus. (He is not only intelligent, but also good-looking.)
4. Entweder … oder (Either … or)
- Wir fahren entweder nach Italien oder wir bleiben zu Hause. (We either travel to Italy or stay home.)
5. Einerseits … andererseits (On the one hand … on the other hand)
- Einerseits möchte ich reisen, andererseits muss ich sparen. (On one hand I want to travel, on the other hand I must save.)
5. Subtle Nuances: Weil vs. Da vs. Denn
How do you choose between weil, da, and denn when explaining a reason?
- Weil (Most Common): Answers a direct question (Warum?). Pushes verb to the end.
- Warum kommst du nicht? ➔ Ich komme nicht, weil ich arbeiten muss.
- Da (Known Cause): Used when the reason is already known to the listener or placed at the beginning of the sentence. Pushes verb to the end.
- Da heute Feiertag ist, haben die Geschäfte geschlossen. (Since today is a holiday…)
- Denn (Expressive / Literary): ADUSO connector (Position 0). Cannot stand at the beginning of a sentence.
- Ich bleibe zu Hause, denn es regnet.
Sentence Structure Summary Matrix
| Connector Group | Example Connectors | Position of Conjugated Verb | Example Sentence |
|---|---|---|---|
| Group 1: Subordinating | weil, dass, obwohl, da, wenn, als | Very END of subclause | Ich bleibe zu Hause, weil es regnet. |
| Group 2: Coordinating (ADUSO) | aber, denn, und, sondern, oder | Position 2 (Connector is Pos 0, no change) | Ich habe Hunger, denn ich bin krank. |
| Group 3: Adverbial | deshalb, trotzdem, außerdem, sonst | Position 2 (Immediately after connector at Pos 1) | Es regnet; deshalb bleibe ich zu Hause. |
