Conjunctions

die Konjunktionen

German conjunctions join two clauses or words by meaning, and they split into groups by how they treat word order: und, aber, denn leave it alone, while deshalb flips subject and verb.

aber leaves the sentence alone, deshalb flips the subject behind the verb. In English a linking word never changes the order, so the second group keeps tripping people up. Here: which conjunctions take up the first slot and which do not, the rule for sondern, and how und lets you shorten a sentence.

01

Right now: two groups, two behaviours

This builds on

If you know the rule “the verb sits in second position”, this page is about who takes up that first slot and who does not.

ShortcutIf the conjunction takes up the first slot, the subject drops behind the verb. und · aber · denn do not take up a slot; deshalb · trotzdem · dann do.

The one law of the German sentence was: the conjugated verb sits in second position. Conjunctions relate to that law in three different ways, and the groups are named after that relationship.

  • Position 0 und · aber · oder · denn · sondern DO NOT TAKE A SLOT · ORDER STAYS
  • Position 1 deshalb · trotzdem · dann · sonst TAKE THE FIRST SLOT · SUBJECT FLIPS
  • Nebensatz weil · dass · wenn · obwohl SUBORDINATE CLAUSE · SEND THE VERB TO THE END

The third box is not the topic of this page — it lives on the subordinate clauses page. Here we only join two main clauses.

02

Position 0: the five that change nothing

These are the easiest conjunctions, and your English instinct works fine here. The conjunction sits in slot zero, so it does not count; after it the clause carries on as if it were starting fresh.

ConjunctionIn EnglishExample
undandIch koche und er deckt den Tisch.
aberbutIch bin müde, aber ich komme mit.
oderorWir gehen ins Kino oder wir bleiben hier.
dennbecause · forIch komme nicht, denn ich bin krank.
sondernbut rather · insteadNicht heute, sondern morgen.

In every row the subject comes right after the conjunction, with the verb behind it. So the clause is not disturbed. An easy way to memorise the five: “und aber oder denn sondern” — it comes out in one breath and sticks within a week.

denn is the most valuable member of this group. It means exactly what weil means — “because” — but it leaves the word order alone. It is the word to grab when you freeze mid-sentence.

Ich komme nicht, denn ich bin krank.

I’m not coming, because I’m sick. → normal order.

Ich komme nicht, weil ich krank bin.

Same meaning, but the verb went to the end.

Both are correct. weil looks better in writing, while denn saves your life when you are speaking. In an exam you need to be able to use both.

03

sondern: the “but” English doesn’t split

aber and sondern are both translated as “but”, and that translation misleads you. The difference between them follows one very clear rule.

ConjunctionWhenExample
aberboth things are true, and they contrast with each otherDas Auto ist alt, aber gut. — Old, but good.
sondernthe first part is negative and the second replaces itDas Auto ist nicht alt, sondern neu. — Not old, but new.

Rule of thumb: if nicht or kein comes first, use sondern, otherwise aber. English has the same split (“not old but new”, “not X but rather Y”) but uses one word for both, so we rarely notice it. German always makes the choice.

Ich trinke keinen Kaffee, sondern Tee.

I’m not drinking coffee, I’m drinking tea.

Ich trinke keinen Kaffee, aber Tee.

Sounds wrong in German.

Read the nicht … sondern pair together with the negation page: without knowing where nicht goes in the sentence, you cannot build this pattern correctly.

04

Position 1: the group that flips the sentence

The second group is not really made of conjunctions but of adverbs. And because they are adverbs, they sit in the first slot of the clause. Once that slot is filled, the verb has to stay second, so the subject drops behind the verb.

WordIn EnglishExampleOrder
deshalbthat’s whyIch bin krank. Deshalb komme ich nicht.flipped
deswegenthat’s whyDeswegen bleibe ich zu Hause.flipped
trotzdemstill · anywayEs regnet. Trotzdem gehe ich raus.flipped
dannthenIch esse. Dann gehe ich schlafen.flipped
danachafterwardsDanach trinken wir Kaffee.flipped
sonstotherwiseBeeil dich, sonst kommen wir zu spät.flipped
außerdembesides · alsoAußerdem habe ich keine Zeit.flipped

The same thing happens in all seven: word → verb → subject. English does this too after words like “never” or “hardly” (“Never have I seen…”), only much more rarely. Once this pattern settles in your ear, you build it without thinking.

TRAP 01

“deshalb ich komme nicht” — mixing up the groups

The most common mistake at A2. Using deshalb like denn, meaning putting the subject right after it. A German ear catches this instantly.

Deshalb ich komme nicht.

Wrong.

Deshalb komme ich nicht.

That’s why I’m not coming.

How to check: delete deshalb and read the clause on its own. Ich komme nicht — verb second. Now put deshalb back at the front: the slot is filled, the verb still has to be second, so the subject shifts.

05

Both groups side by side: one meaning, three ways

You can express the same cause and effect with three different conjunctions, and each one lines the sentence up differently. Once you see it in a table, the system clicks:

ConjunctionGroupSentence
dennPosition 0Ich komme nicht, denn ich bin krank.
weilsubordinate clauseIch komme nicht, weil ich krank bin.
deshalbPosition 1Ich bin krank, deshalb komme ich nicht.

Note that deshalb also turns the logic of the sentence around. denn/weil says “I’m not coming ← because I’m sick”, deshalb says “I’m sick → that’s why I’m not coming”. Cause and effect swap places.

For contrast there is the same trio, with exactly the same logic:

ConjunctionGroupSentence
aberPosition 0Es regnet, aber ich gehe raus.
obwohlsubordinate clauseIch gehe raus, obwohl es regnet.
trotzdemPosition 1Es regnet, trotzdem gehe ich raus.

These six rows are the backbone of the A2 written exam. “Rewrite the same sentence with a different conjunction” is exactly what they ask.

06

The part nobody tells you: und shortens the sentence

Textbooks wave und through as “and”. In real German, after und you drop the repeated subject — and a sentence that doesn’t do this sounds like a beginner. English does the same (“I get up and go to the bathroom”).

Ich stehe auf und ich gehe ins Bad.

Correct but heavy — the subject appears twice.

Ich stehe auf und gehe ins Bad.

I get up and go to the bathroom. — this is the natural one.

Rule: if both clauses have the same subject, you can drop it in the second one. If the subject changes, you cannot drop it.

Ich koche und er deckt den Tisch.

The subject changed — it can’t be dropped.

The same shortening works with aber · oder, but not with denn: after denn the subject is compulsory.

Ich komme nicht, denn ich bin krank.

The subject can’t be dropped.

Ich komme nicht, denn bin krank.

Wrong.

What you just learned

  • He isn’t coming; on the contrary, he’s staying at home. Er kommt nicht, ___ er bleibt zu Hause.

    Show the answer

    sondern — When you deny something and state the opposite, you use sondern.

  • After the conjunction und, the verb always comes right at the start of the clause (in second position).

    Show the answer

    False. und is in Position 0, so it does not disturb the word order of the clause. The subject has to come after it.

  • Ich bin krank. Deshalb ___ nicht.

    Show the answer

    komme ich. deshalb occupies the first slot; since the verb has to stay in second position, the subject drops behind it.

What to do this week

This topic sticks by writing one sentence three times. A five-minute daily exercise:

  • Pick a cause-and-effect sentence from your day: “I was tired, so I went to bed early.”
  • Build it with denn: Ich bin früh ins Bett gegangen, denn ich war müde.
  • Build it with weil — the verb goes to the end: …, weil ich müde war.
  • Build it with deshalb — the subject flips: Ich war müde, deshalb bin ich früh ins Bett gegangen.
  • Repeat the same trio for contrast: aber · obwohl · trotzdem.

Next up: subordinate clauses — every conjunction that sends the verb to the end, plus the difference between wenn · wann · als.

Tips

Know this before the test

The core of the topic in three lines, then the mistakes people make most often.

  1. Position 0: und · oder · aber · denn

    These four never disturb the word order: subject + verb follow them in the normal order.

    Ich komme nicht, denn ich bin krank.

  2. Position 1: deshalb · trotzdem · dann

    These fill the first slot of the clause; the verb comes right after them, and the subject drops behind the verb.

    Ich bin krank. Deshalb komme ich nicht.

  3. sondern only after a negative

    sondern means “but rather” and only corrects a negative clause: nicht X, sondern Y. For a plain contrast, use aber.

    Ich trinke keinen Kaffee, sondern Tee.

  4. weil sends the verb to the end, denn does not

    Both give a reason, but weil builds a subordinate clause (verb last) while denn leaves a main clause (verb second). The verb’s position gives away which one was used.

    …, weil ich krank bin. · …, denn ich bin krank.

  • Deshalb ich komme nicht.

    Deshalb komme ich nicht.

    deshalb fills the first slot; the verb moves to second position.

  • Ich trinke keinen Kaffee, aber Tee.

    Ich trinke keinen Kaffee, sondern Tee.

    The conjunction that corrects a negative and gives the right version is sondern.

  • Ich komme nicht, denn ich krank bin.

    Ich komme nicht, denn ich bin krank.

    denn does not build a subordinate clause; the verb stays where it is.

  • Es regnet, trotzdem ich gehe raus.

    Es regnet, trotzdem gehe ich raus.

    trotzdem also fills the first slot: the verb comes right after it.

Test yourself

Tap an answer — we will look at why together.

Ich bin krank. Deshalb nicht.

I’m sick. That’s why I’m not coming.

komme ich. deshalb occupies the first slot; since the verb has to stay in second position, the subject drops behind it.

Ich komme nicht, denn krank.

I’m not coming, because I’m sick.

ich bin. denn does not occupy a slot (Position 0) — the clause carries on in normal order after it.

Ich trinke keinen Kaffee, Tee.

I’m not drinking coffee, I’m drinking tea.

sondern. There is a kein before it: the first part is negated and the second replaces it. Without the negation, aber would be used.

Which one is correct?

trotzdem gehe ich raus. trotzdem is in Position 1 — it flips the subject. The only group that sends the verb to the end is the subordinating conjunctions (like obwohl).

Ich stehe auf und ins Bad.

I get up and go to the bathroom.

gehe. If both clauses have the same subject, it is dropped after und — that is natural German. ich gehe isn’t wrong, but it sounds heavy.

Ich lerne Deutsch, ich in Berlin arbeiten will.

I’m learning German because I want to work in Berlin.

The verb (will) is at the end of the clause — this is a subordinate clause, so the conjunction is weil. With denn the verb would stay in second position.
