Learn Danish: Inspektionen er forsinket for så vidt som hun skal tjekke adskillige partier. - The inspection is delayed insofar as she has to check several batches.

For så vidt som translates to "insofar as" or "inasmuch as." It acts as a multi-word subordinating conjunction, which means the clause that follows it (hun skal tjekke adskillige partier) is a subordinate clause.

If there were a central adverb like ikke in the second half of the sentence, where would it go?

Because for så vidt som introduces a subordinate clause, the standard rule of placing the central adverb before the verb applies. If she did not have to check them, it would be: for så vidt som hun ikke skal tjekke adskillige partier.

What does adskillige mean, and how does it compare to flere or mange?

Adskillige means "several" or "quite a few." It implies a solid number greater than just a couple, but often not quite as high as mange (many). It is slightly more formal and emphatic than simply using flere (several).

Why is the word partier used for "batches"? Doesn't that mean "parties"?

Yes, et parti is commonly used for a political party. However, in a business, manufacturing, or logistics context, it is also the standard word for a "batch," "lot," or "consignment" of goods. Here, she is inspecting multiple batches of items.

Is er forsinket considered a passive construction here?
