How to use "deshalb" in a German grammar

"Deshalb" is one of the most useful connecting words in German: it lets you link a reason to its consequence — "he overslept, that's why he was late" — in a single, natural-sounding structure. The good news is that once you know the sentence pattern, "deshalb" is genuinely easy to use correctly. This lesson covers that pattern, plus the most common point of confusion: the difference between "deshalb" and the similar-looking "weshalb," along with the most useful synonyms for "deshalb."

What "deshalb" Means and How It Works

Deshalb means "therefore" or "that's why," and it connects a reason (Grund) to its consequence (Konsequenz):

Er hat verschlafen, deshalb kommt er zu spät zur Arbeit. — He overslept, that's why he's late for work.

Deshalb is a conjunctional adverb (Konjunktionaladverb), not a subordinating conjunction like "weil." That distinction matters because it determines the word order.

The Sentence Structure

Since "deshalb" is an adverb, it takes up position 1 in its own clause, which means the verb has to come immediately after it, in position 2 — exactly like any other sentence that starts with an adverb:

Es hat stark geregnet. Deshalb ist das Spiel abgesagt worden. — It rained heavily. That's why the game was cancelled.

You can also join the two clauses with a comma instead of a full stop, and the word order rule stays exactly the same — the verb still comes directly after "deshalb":

Ich habe keine Zeit, deshalb kann ich nicht kommen. — I don't have time, that's why I can't come.

"Deshalb" vs. "Weshalb"

These two look almost identical, but they do different jobs. Weshalb is primarily a question word meaning "why," used exactly like "warum": Weshalb bist du zu spät? — Why are you late? Weshalb can also work as a relative connector inside a single sentence, meaning "which is why" — in that use, it sends the verb to the end of its clause, like a subordinating conjunction: Er hat verschlafen, weshalb er zu spät kam. — He overslept, which is why he was late. Notice the verb position difference: with deshalb, the verb comes right after it (position 2); with weshalb used this way, the verb goes to the very end of the clause.

Synonyms for "deshalb"

Several other words mean essentially the same thing as "deshalb" and follow the identical word-order rule (verb directly after them): daher, darum, deswegen, and the slightly more formal aus diesem Grund. All of these can be swapped in for "deshalb" without changing the meaning, which is useful both for understanding native speakers and for varying your own writing.

Ich war krank, darum konnte ich nicht kommen. — I was sick, that's why I couldn't come.

Sie hat viel geübt, deswegen hat sie die Prüfung bestanden. — She practiced a lot, that's why she passed the exam.

Frequently Asked Questions

What does "deshalb" mean in German?

"Deshalb" means "therefore" or "that's why" — it connects a reason to its consequence, e.g. "Er hat verschlafen, deshalb kommt er zu spät" (He overslept, that's why he's late).

What is the word order after "deshalb"?

"Deshalb" takes position 1 in its clause, so the verb must come immediately after it in position 2, e.g. "Deshalb ist das Spiel abgesagt worden" (That's why the game was cancelled).

What is the difference between "deshalb" and "weshalb"?

"Weshalb" is mainly a question word meaning "why" (a synonym of "warum"). It can also connect two ideas within one sentence meaning "which is why," but in that use it sends the verb to the end of the clause — unlike "deshalb," which keeps the verb in position 2.

What are some synonyms for "deshalb"?

"Daher," "darum," "deswegen," and the more formal "aus diesem Grund" all mean essentially the same as "deshalb" and follow the same word-order rule.

Can "deshalb" start a new sentence, or does it need a comma?

Both work. You can either join the reason and consequence with a comma ("Ich habe keine Zeit, deshalb kann ich nicht kommen") or write them as two separate sentences ("Ich habe keine Zeit. Deshalb kann ich nicht kommen."). The word order rule after "deshalb" stays the same either way.

Connecting words like these get a lot more natural with practice — which is exactly what our A2 German course offers.
