Cool, German for torturers!
We have ways...
Is there any difference between ´reden´ and ´sprechen´?
Yes and no. For certain situations or idioms the one or the other gets preferred, but there is no real difference in the meaning.
Loks like reden is more like a speech, where only one person talks.
No. For a speech, you will prefer to say reden, but you also can use reden when you have a chat with other persons.
I wrote "of course he will give a speech" and was marked wrong. Report?..
I believe that would be (literally)
Natürlich wird er eine Rede geben.
They did not use the noun "die Rede" in this question, so I would not report.
What about obviously he will talk ?
Selbstverständig wird er reden.
Why not He will talk for sure?
No reason that you can put "of course" at the end
Wir warten nur für wenn.
"Of course he will talk" or "he will talk of course"? Why is the first accepted and not the other?
They probably should both be accepted. Feel free to report it.
How to say "he will talk naturally"?
Er wird natürlich sprechen. Word order is key here.
Wrote: "Eventually he will talk", cause in my messed up torturing mind it sounded better ;DD didn't accepted though :(
naturally will he speak OR naturally he will speak OR naturally he'll speak
alle sind gleich
"Naturally will he speak" makes no sense - the word order is wrong
It's actually an archaic word order, but you probably won't come across it unless you're reading the KJV or Shakespeare or something like that.
