Questions & Answers about Als er das Haus gekauft hat, hat alles perfekt geklappt.
Why use als for 'when' here instead of wenn?
In German, als is used exclusively for a single, one-time event in the past (like buying this specific house). You use wenn for present or future events, or for repeated past events ('whenever'). Since your current lesson covers time conjunctions like solange ('as long as'), it is helpful to remember that als, wenn, and solange all trigger the exact same word order rules, even though they describe entirely different time frames!
Why is the first hat at the very end of its clause?
Als is a subordinating conjunction, exactly like solange ('as long as'). These conjunctions 'kick' the conjugated verb to the very end of their clause. So instead of the normal word order er hat das Haus gekauft, the conjunction forces it to be Als er das Haus gekauft hat.
Why does the second half of the sentence start with hat alles instead of alles hat?
The entire first clause (Als er das Haus gekauft hat) acts as a single block that occupies the first position in the sentence. Because German main clauses demand that the conjugated verb sits in the second position, the verb hat must come immediately after the comma. This forces the subject alles to move after the verb, creating the classic 'verb, verb' pattern you see here: ... gekauft hat, hat alles ...
What does geklappt mean here? I thought 'to work' was arbeiten.
While arbeiten means 'to work' in the sense of doing a job or labor, the verb klappen is used when something 'works out', 'functions', or 'goes smoothly'. It is an essential verb for everyday German. If a plan or a situation goes perfectly, you say Es hat geklappt! ('It worked out!').
