Learn Swedish: Kaptenen bekräftade turbulensen innan starten. - The captain confirmed the turbulence before the takeoff.

The noun starten (the takeoff) replaces a full subordinate clause. Instead of saying innan planet startade (before the plane took off), the sentence uses the noun form of the verb att starta to make the phrase more concise and formal.

The lesson mentions using a genitive modifier. How would we apply that here if we wanted to specify that it was the plane's takeoff?

You would change the definite noun starten to an indefinite noun modified by a genitive (possessive) noun. The phrase would become innan planets start (before the plane's takeoff) instead of just innan starten.

Why is innan used here before a noun phrase (starten) instead of före?

Traditionally, före is a preposition used before nouns (like före starten), and innan is a conjunction used before clauses (like innan planet startade). However, in modern Swedish, it is extremely common and fully accepted to use innan as a preposition before nouns too. Both innan starten and före starten are correct here.

Could turbulensen also be considered a nominalization in this context?

Yes! Instead of using a full clause like Kaptenen bekräftade att det var turbulent (The captain confirmed that it was turbulent), the concept is transformed into the definite noun turbulensen. This packs the same meaning into a shorter, more professional-sounding sentence.
