What's the difference between weil and denn?

Both mean "because", but they work differently. "Weil" is subordinating — the verb goes to the end: "Ich gehe, weil ich müde bin." "Denn" is coordinating — verb stays in position 2: "Ich gehe, denn ich bin müde." In speech, "weil" is far more common. "Denn" sounds slightly more formal. If you can only learn one, learn weil.

When should I use als vs wenn?

"Als" is for a single event in the past: "Als ich jung war, spielte ich Fußball." "Wenn" covers repeated past events and all present/future conditions: "Wenn es regnet, bleibe ich zu Hause." The test: could the event happen again? If yes, use "wenn". If it's a unique one-off past memory, use "als".

How many connectors do I need for B1?

The Goethe B1 exam writing rubric explicitly scores for "Kohäsion" (cohesion) — variety of connectors. Examiners are instructed to penalize writing that relies only on "und" and "aber". Aim for at least 5 distinct connectors per short essay, spanning at least 2 types (e.g., coordinating + subordinating).

Why does the verb jump to the end after weil?

Subordinating conjunctions create a "subordinate clause bracket" (Satzklammer) — the main verb must park at the right end of that bracket. This is the core rule of German word order. Think of the subordinating conjunction as opening a bracket that closes with the verb at the end.

Can I use trotzdem and obwohl interchangeably?

Not interchangeably — they play different grammatical roles. "Obwohl" is subordinating (verb to end): "Obwohl es regnet, gehe ich raus." "Trotzdem" is adverbial (inversion if clause-initial): "Es regnet. Trotzdem gehe ich raus." They express the same logical relationship ("despite X") but sit in different positions and trigger different word-order rules.

German connectors — the words that determine your word order

30 conjunctions in 3 types. Coordinating keeps verb 2nd. Subordinating sends verb to the end. Adverbial triggers inversion.

German word order is not random — it follows rules, and connectors are the trigger that activates those rules. Pick the wrong connector type and your word order breaks. Pick the right one and your sentence clicks into place.

Connectors also unlock your writing score. Variety across all 3 types is what the B1 exam writing rubric rewards. The learners who stay at "und, aber, oder" are leaving marks on the table.

Coordinating

Keeps V2 in both clauses — simplest case

Word	Meaning	Example	Word Order
und	and	Ich komme, und ich bringe Wein. I'm coming, and I'm bringing wine.	—
aber	but	Ich komme, aber ich bin spät. I'm coming, but I'm late.	—
oder	or	Wir gehen ins Kino oder wir bleiben zu Hause. We go to the cinema or we stay home.	—
denn	because (causal)	Ich gehe nach Hause, denn ich bin müde. I'm going home because I'm tired.	Note: denn = because as coordinating. Different from weil (subordinating).
sondern	but rather / but instead	Nicht Tee, sondern Kaffee. Not tea, but coffee.	Used after a negative to correct it — "not X, but Y".
doch	but / yet (contrary)	Er wollte nicht kommen, doch er kam. He didn't want to come, yet he came.	—
allein	however / but (formal)	Er wollte lernen, allein die Zeit fehlt. He wanted to study, but time is lacking.	Rare in speech — mostly written formal German.

Subordinating

Verb goes to the END of the subordinate clause

Word	Meaning	Example	Word Order
weil	because	Ich komme nicht, weil ich krank bin. I'm not coming because I'm sick.	Verb to end. If the subordinate clause comes first, invert main clause: "Weil ich krank bin, komme ich nicht."
dass	that	Ich weiß, dass er kommt. I know that he's coming.	—
wenn	if / when (repeated or conditional)	Wenn es regnet, bleibe ich zu Hause. If it rains, I stay home.	Use for repeated past events and conditions. For a single past event, use "als".
obwohl	although / even though	Obwohl es regnet, gehe ich raus. Although it's raining, I'm going out.	—
da	since / because (formal)	Da er krank ist, kommt er nicht. Since he's sick, he's not coming.	More formal than "weil" — common in written German and clause-initial position.
als	when (single past event)	Als ich jung war, spielte ich Fußball. When I was young, I played football.	Only for single past events. For repeated/conditional, use "wenn".
bis	until	Warte, bis ich komme. Wait until I come.	—
damit	so that / in order that	Ich lerne, damit ich die Prüfung bestehe. I study so that I pass the exam.	—
ob	whether / if (indirect question)	Ich weiß nicht, ob er kommt. I don't know whether he's coming.	—
bevor	before	Bevor ich gehe, trinke ich Kaffee. Before I go, I drink coffee.	—
nachdem	after	Nachdem ich gegessen hatte, schlief ich. After I had eaten, I slept.	Often uses Plusquamperfekt (past perfect) in the subordinate clause.
falls	in case / if (contingency)	Falls es regnet, nehme ich den Schirm. In case it rains, I'll take the umbrella.	Implies contingency — more uncertain than "wenn".

Adverbial

Triggers inversion when at clause start

Word	Meaning	Example	Word Order
trotzdem	nevertheless / still	Es regnet. Trotzdem gehe ich raus. It's raining. Nevertheless, I'm going out.	At sentence start: verb jumps forward (Trotzdem GEHE ich).
deshalb	therefore / that's why	Ich bin müde. Deshalb gehe ich schlafen. I'm tired. That's why I'm going to sleep.	—
deswegen	therefore / for that reason	Es ist kalt. Deswegen ziehe ich eine Jacke an. It's cold. For that reason I'm putting on a jacket.	Synonymous with deshalb, slightly more colloquial.
dann	then / afterwards	Wir essen, dann gehen wir spazieren. We eat, then we go for a walk.	—
danach	afterwards / after that	Wir gehen essen, danach ins Kino. We're going to eat, after that to the cinema.	—
außerdem	furthermore / in addition	Das Wetter ist schlecht. Außerdem bin ich müde. The weather is bad. In addition, I'm tired.	—
dennoch	nevertheless / still (more formal)	Es war schwer. Dennoch habe ich es geschafft. It was hard. Nevertheless, I managed it.	More formal register than "trotzdem".
allerdings	however / though / admittedly	Das ist interessant. Allerdings ist es teuer. That's interesting. However, it's expensive.	—
jedoch	however / but (written)	Er kommt. Jedoch ist er spät. He's coming. However, he's late.	More formal — common in written German. "Aber" is the spoken equivalent.
daher	therefore / hence	Es war kalt. Daher blieb ich zu Hause. It was cold. Hence I stayed home.	—
sonst	otherwise / else	Beeil dich, sonst kommen wir zu spät. Hurry up, otherwise we'll be late.	—

Writing tip: connector variety

The Goethe B1 exam writing rubric scores "Kohäsion" — cohesion. Examiners are trained to look for connector variety. A response that uses only und and aber scores in the lowest cohesion band regardless of content quality.

Target at least 5 distinct connectors per short essay (200 words)
Cover at least 2 connector types — e.g., coordinating + subordinating
Add one adverbial connector at clause start for instant variety
Causal connectors (weil, denn, da) are especially valued
