Learn Dutch: Het karretje schudde het hardst tijdens de tweede looping. - The cart shook the hardest during the second loop.

How would you rewrite this sentence to say 'Only during the second loop did the cart shake the hardest', applying the restrictive fronting rule from this lesson?

You would start with the restrictive adverb pas (only/not until) combined with the time phrase. This triggers V2 inversion, forcing the verb to come right after the fronted element and before the subject: Pas tijdens de tweede looping schudde het karretje het hardst.

Why is it het hardst and not just hardste or hardst?

When a superlative is used as an adverb (describing how an action is done, rather than modifying a noun), Dutch requires you to use het before it and add no extra -e at the end. Because it describes how the cart shook, it must be het hardst.

Is looping just an English word, and why is it de tweede looping instead of het?

Yes, Dutch often borrows English words ending in '-ing' to use as nouns (like de meeting or de training). These English '-ing' loanwords almost always take the de article. In Dutch, de looping specifically refers to a roller coaster loop.

The verb schudde has a double 'd'. Why isn't it just schude?
