Learn Swedish: De har förmodligen accepterat både priset och datumet. - They have presumably accepted both the price and the date.

In a Swedish main clause, sentence adverbs like förmodligen (presumably/probably) go right after the first verb. When you have a helping verb (har) and a main verb (accepterat), the adverb steps right between them.

Are förmodligen and antagligen interchangeable?

Yes, for the most part! Both mean "probably" or "presumably" and are used to show your level of certainty. Förmodligen comes from the verb förmoda (to suppose) and can sound slightly more formal than antagligen, but you can use either one here.

How do we use the både ... och structure in Swedish?

Både ... och translates to "both ... and". Just like in English, you wrap it around the two items you are connecting. Here, it connects two nouns: både priset och datumet (both the price and the date).

Why do both pris and datum end in -et here?

In Swedish, "both the price and the date" requires the definite form. Because pris and datum are both ett words, they take the -et suffix to mean "the" price and "the" date (priset, datumet).
