Questions & Answers about Schließlich liegt er wieder schnarchend im Bett.
How do we form the word schnarchend, and what is its role here?
schnarchend is a Present Participle (Partizip I). You form it simply by adding a -d to the infinitive of the verb schnarchen (to snore). In this sentence, it acts as an adverb of manner describing exactly how he is lying.
Since schnarchend describes the man, why doesn't it have an ending like schnarchender?
Because it is used as an adverb modifying the verb liegt (he lies snoring), rather than an adjective modifying a noun. When a present participle functions as an adverb, it remains in its base form and takes no endings. It would only get an ending if it were placed directly before a noun, like der schnarchende Mann (the snoring man).
Why are the words ordered as wieder schnarchend im Bett?
This follows the classic Time-Manner-Place rule for word order in German. We start with wieder (Time/Frequency), follow it with the manner in which he is doing it (schnarchend), and end with the location (im Bett).
Why do we use the dative im Bett here instead of the accusative ins Bett?
