While I understand what you mean, that is only because I speak English too. Swedish så doesn't work the way English so does here, instead you have to go for det and say "det hoppas jag" or "jag hoppas det", preferrably the former to refer back to the statement above.
tack! what I know about "så" is only from Duolingo phrases... I haven't studied deeper "så" yet..
I'm only just now beginning to notice how Swedish is pronounced, which I find extremely difficult. I never hear a real person speak the language. Should "redan" really be stressed the way it is here?
if you want to hear real persons speak swedish you could watch swedish vloggers on youtube or you could watch swedish netflix series(I watched quicksand with swedish subtitles and I understood it and it really improved my swedish)
If you're willing to pay a little, there are a lot of good shows (well, depending what you're into, I guess) on the MHz Choice channel on Amazon in Swedish with subtitles in English. There's also svtplay.com. A lot of the shows can only be viewed if you're inside the country (or connected to a VPN), but there are a lot you can watch utomlands as well, with Swedish subtitles.
