Questions & Answers about Weißt du, ob man ein fruchtiges Bier brauen könnte?
How is the adjective fruchtiges formed from a noun?
It comes from the noun die Frucht (the fruit). By adding the suffix -ig, we create the base adjective fruchtig (fruity). Finally, we add the ending -es because it describes a neuter noun (das Bier) in the accusative case following the indefinite article ein.
Why does the verb könnte go at the very end of the sentence?
The word ob (whether or if) is a subordinating conjunction. It introduces a dependent clause and forces the conjugated verb, which is könnte here, to move all the way to the end of the sentence, safely past the infinitive brauen.
Why do we use könnte instead of kann here?
The word könnte is the Subjunctive II form of können (can). We use it here to express a theoretical possibility (could one brew it?) rather than a hard fact. It makes the question sound hypothetical and polite.
What is the role of the word man in this sentence?
The word man is an indefinite pronoun that translates to one or the general you. The speaker uses it because they aren't asking if you specifically can brew the beer, but rather if it is generally possible for anyone to do it.
