"He is going to quit drinking coffee."
Translation:Han ska sluta dricka kaffe.
Han kommer att sluta dricka kaffe. How does this sentence differ from the one above?
The one with kommer att is more of an objective prediction that this is going to happen. In Han ska …, there's somebody who wants this to happen, in this case, most likely he himself.
When can you have two infinitives in a row? Does it only happen after sluta?
