Incredibly useful summary
Whilst learning German, I have referred back to this "cheat sheet" frequently, and thought I should share it. It has been incredibly useful for me, especially considering the variety of information.
If you don't understand everything on there now, don't worry. You will eventually (hopefully).
--> Group A relates to 'normal' (strong) endings. --> Group B relates to adjective endings preceded by 'ein-' or 'der-' word.
Note the red exceptions, including for either 'ein-' or 'der-' words below the table.
Good luck :)
I just wanted to add my thoughts as someone who doesn't need the "cheat sheet":
First of all:
Nice! It's got a bunch of the toughest stuff all together that you can refer to in one place, so I think that should be really handy to a lot of people.
On the other hand I did (and do) find it a bit confusing, probably because of the sheer amount of information being condensed to a single page. I can see how the strong, weak and mixed inflections are all in there now, but I imagine for someone who doesn't know what strong, weak and mixed inflections are, they might need a bit of help first.
Obviously, being a cheat sheet, anyone using it should read up on each section fully elsewhere, and then come back to this as a reference, so that's not too big of an issue.
The other issue I found was the inclusion of some supposedly "common" genitive prepositions i.e. „oberhalb“, „unterhalb“ and „diesseits“. I wonder who classes these as common, because I hadn't come across them before I saw them on the cheat sheet.
Now, in fairness, their meanings are each reasonably easy to guess at (and actually the fact that they would require the genitive case) when you're familiar with German; but the fact still remains that they are being paraded around as common, when I haven't noticed them in any of the articles, books, films, TV shows or youtube videos that I have read/watched.
All in all, a handy cheat sheet me thinks!
P.S. I just noticed there is an error for the genitive form of „man“, which it has as „sein“; when in actuality „man“ has no genitive form.
