Yepp, I think it is used in a similar way as in the English language (and German?)

They do. De and dem are both said as were they written dom.

Kommer att also means ’will, going to’ and is used to create the future tense. Compare to English ’go’ which both means ’to go somewhere’ and ’going to’ which creates the future (’I am going to do that.’)

The word on its own means ’to come’ however.
