Questions & Answers about Ehe man das Handwerk lernt, übt man, das Metall zu biegen.
How is ehe different from bevor in this sentence?
Both ehe and bevor mean "before" and function as subordinating conjunctions, which means they both send the conjugated verb (lernt) to the end of their clause. Ehe is slightly more formal or literary than bevor, but they are completely interchangeable here. You could easily say Bevor man das Handwerk lernt without changing the meaning.
Why does the main clause start with the verb übt?
This is because of the V2 (verb-second) rule. The entire subordinate clause (Ehe man das Handwerk lernt) acts as a single conceptual block occupying the first position of the sentence. To keep the main conjugated verb in the second position, übt must immediately follow the comma.
Why is there a comma before das Metall zu biegen?
That part is an extended infinitive clause (an infinitive phrase with its own object, das Metall). While modern German spelling rules have made commas optional for some simple infinitive clauses, it is highly recommended and often required to separate longer infinitive clauses with a comma to make the sentence structure clear.
Could I say ...übt man das Metall biegen without the zu?
