Questions & Answers about Zwecks einer Einigung sprechen wir mit dem Mediator.
What kind of word is zwecks, and what case does it require?
Zwecks comes from the noun der Zweck (the purpose). In formal and business German, it is used as a preposition meaning 'for the purpose of.' Like many formal prepositions, it requires the genitive case, which is why it is followed by the feminine genitive einer Einigung.
If I wanted to include an -ermaßen adverb from this lesson, like bekanntermaßen (as is well known), where would it go in this sentence?
In German, adverbs usually sit directly after the conjugated verb and the subject. You would place it right after wir: Zwecks einer Einigung sprechen wir bekanntermaßen mit dem Mediator. Alternatively, you could start the sentence with it: Bekanntermaßen sprechen wir zwecks einer Einigung mit dem Mediator.
Could I express this same meaning using um ... zu (in order to)?
Yes, but the grammar would shift. Zwecks is a preposition used directly with a noun (einer Einigung). The um ... zu construction requires an infinitive verb phrase. You would have to rephrase it as: Um uns zu einigen, sprechen wir mit dem Mediator (In order to reach an agreement, we are speaking with the mediator).
Why does the verb sprechen come before the subject wir?
