Questions & Answers about Bevor ich schlafen gehe, gehe ich kurz ins Bad.
Because bevor introduces a subordinate clause (Bevor ich schlafen gehe). In German, subordinate clauses are separated from the main clause with a comma:
- Bevor ich schlafen gehe, (subordinate clause)
- gehe ich kurz ins Bad. (main clause)
That comma is basically mandatory in standard written German.
In subordinate clauses introduced by subordinating conjunctions like bevor, the conjugated verb goes to the end of the clause. So instead of ich gehe schlafen, you get:
- Main clause word order: Ich gehe schlafen.
- Subordinate clause word order: ..., bevor ich schlafen gehe.
Here, gehe is the conjugated verb, so it moves to the end.
It’s a common verb combination: gehen (to go) + an infinitive (schlafen) to mean to go (and) sleep / to go to bed.
- schlafen is the infinitive describing the purpose/activity.
- gehen is the main verb that gets conjugated (ich gehe).
So Ich gehe schlafen is idiomatic for I’m going to sleep / I’m going to bed.
