Questions & Answers about Wir brauchen einen Assistenten, dessen Kompetenz so hoch ist, wie unser Standard es verlangt.
Why is there a comma before wie in this sentence, when we usually see so hoch wie written together?
In this sentence, wie introduces a full subordinate clause. Because it contains its own subject (unser Standard) and pushes the conjugated verb (verlangt) to the very end, it must be set off by a comma. If you were just comparing two nouns or adjectives without adding a new verb (like so hoch wie ein Berg - 'as high as a mountain'), you wouldn't use a comma.
Why do we use dessen instead of deren, considering Kompetenz is a feminine noun?
dessen is the genitive relative pronoun meaning 'whose'. Its form depends only on the gender and number of the noun it refers back to, not the noun that comes immediately after it. Since it refers back to einen Assistenten (masculine singular), we use dessen. If we were referring back to a feminine noun, like eine Assistentin, we would use deren.
Is Assistenten plural here? Why does it have an -en ending?
It is singular here ('an assistant'). Assistent belongs to a group of masculine nouns known as 'weak nouns' (the n-declension). These nouns—often ending in -ent, -ant, or -ist—take an -en or -n ending in every case except the nominative. Because the assistant is the direct object (accusative) of the verb brauchen, it takes the -en ending: einen Assistenten.
