I agree, I've turned off the listen-and-type exercise since it's too tricky.
These two sentences do sound very much the same in real life so I still think the TTS is actually pretty good here.
This feels like a bit of a literal translation. It feels a bit clunky in english. Would 'It's an honour for us' be more appropriate?
If there is an adverb or prepositional phrase at the beginning of the sentence, the verb goes after the subject. In this sentence, "för oss" is a prepositional phrase, so "är" (the verb) goes before "det" (the subject). Another example: I morgon vill jag dricka mycket vatten. -- Tomorrow I want to drink a lot of water. or Troligtvis sjunger han. -- Probably he sings.
Is this just a more accurate version of the V2 rule or is it something else?
It basically is the V2 rule, but for someone reason I prefer to think of it as "adverbs/prepositional phrases go first" (at least it's usually adverbs or prepositional phrases).
A is used for words that start with a consonant sound, ie: a House. An is for words that start with a vowel sound, ie: an (h)onor.
