Questions & Answers about Не успел он приехать домой, как пошёл ливень.
Why does the second part of the sentence start with как when the English translation uses "than"?
In the не успел... как... (no sooner had... than) construction, the second clause must always be introduced by как. Even though English uses "than", you cannot use чем or когда here.
Why is the subject он placed after the verb (Не успел он...)?
This inverted word order is standard for the не успел... как... structure. While Он не успел приехать... is grammatically possible, putting не успел at the very beginning emphasizes the dramatic, immediate sequence of the two events.
Does the infinitive verb after не успел have to be perfective like приехать?
Yes, almost always. The phrase describes an action that was just completed a split second before the next event occurred. The perfective aspect of приехать captures this focus on the completed result (having arrived).
I know идёт дождь means "it is raining", but what exactly does the perfective verb пошёл mean with ливень?
Adding the prefix по- to a verb of motion often indicates the sudden start of an action. Here, пошёл ливень doesn't just mean a downpour was happening, but specifically that it suddenly started to pour right at that moment.
