When to use que and when not to
Whats the difference between saying something like " que dios te bendiga " and " dios te bendiga "
The first can be a wish or a hope. The second looks like a statement and should probably read "dios te bendice".
Just to mention it:
In a previous thread it was pointed out that many of these exhortations are "clipped" sentences.
[Espero ] que dios te bendigas.
which is why the subjunctive is required. Remove the que and we are no longer in a subordinate clause where we normally use the subjunctive. (as Eddy points out).
