Sie v Ihnen?
When should I use Sie (formal) or Ihnen? For example, "Darf ich Sie herumfuhren, um Ihnen die anderen Kollege vorstellen?
As jzsuzsi has aced your question, I thought I would just mention that I believe your example sentence should read:
„Darf ich Sie herumführen, um Ihnen die anderen Kollegen vorzustellen?
With an umlaut on the "u" in "herumführen" and a "zu" in "vorzustellen".
EDIT: + "n" in "Kollegen" thanks to gSY55q97
Ich muss schon sagen (und ich glaube, dass ich für Duolingos ganze deutschlernende Gemeindschaft spreche), dass die Arbeit, die du und all der anderen Deutschmuttersprachler hier auf Duolingo machen, um unser (als Deutschlerner/innen) Deutsch zu verbessern, wird sehr dankbar bekommen.
Wir wissen (oder zumindest sollen wissen), dass ihr uns nicht helfen müsst, aber ihr helft uns trotzdem.
I want to say yes.
I'm certain that words longer than 6 letters appear regularly in my exercises (though I wouldn't be surprised if "6" was a slight exaggeration on your part), and having completed the entire tree; all topics and grammar areas covered in the duolingo course can (and do) come up in the exercises I do.
However, if I can remember the difficulty at level 15 (and it was a little while ago), I don't feel that it was all that much easier than it is now. Certainly, if you haven't covered major grammar areas like the past tense or the genitive case, then there will be a noticeable difference in difficulty; but generally speaking I don't think the difficulty hikes up particularly as you get to the dizzying heights of level 25 (tongue firmly in cheek re:"dizzying heights" :).
Don't know if that was encouraging or depressing, but I hope I could help.
Hi Adam, Thanks, I was being a bit provocateur about the six letters, but it does seem Duolingo will never break out of 'easy reader' mode. I have gone back over Duo Dative & Genitive today. Its been some time since I last addressed them. Is level 25 the top level?I might try and push on. regards, Rob
I'd be lying if I said one doesn't need a comprehensive understanding of the cases (conscious or otherwise) to excel with this language.
Level 25 is indeed the top level. Pushing on is of course only a decision you can make, and of course there are plenty of other resources available if you decide you want to move away from duolingo,
but I would recommend pushing on.
Mit freundlichen Grüßen
I have been spending time on Babbel, since I got bored with lvl.15. I have to pay to get good lessons, currently £30/yr special offer, but it gives realistic conversation's at normal speed. So I think, using Duo for grammar and general vocab & Babbel for specific topics could strike the right balance. Alles Gute
