Schwedische Grammatik

1. Jag vill, att det regnar nu.

2. Jag vill att det börjar att regna.

2. Is not usual, because in according to 2 (as a swede would think about it) you want that it should be starting to rain at this moment.

But you know that it is not starting at the same moment as you say it.

Therefor it is more common to say (in swedish):

Jag vill att det ska börja (att) regna.
