Could be clearer?

Question

The lesson doesn't highlight the point that you can swap clauses around - so e.g. start with conditional, then go to imperfect or v.v.  Whichever way though, what changes is the position of 'si' and hence if you are using the imperfect as first or second verb.

Answer

The Si-clause always uses the imperfect whereas the conditional is used only in the main clause. If you switch the order of clauses, naturally, the verb forms switch places too, so that the imperfect remakns with the Si-clause and the conditional with the main clause.

Answer

Hi - tks. I think I got that - my point was that hadn't been made clear in the lesson.

Answer

Hi David, I see what you mean. There is only one example which has the si-clause come second. Maybe a couple more examples and a sentence alerting the reader to this fact would help.
