Dear Prof, Excuse my ignorance, but as a Latin student, we abbreviate the accusative as 'ACC', rather than 'AKK'. I have no academic authority to correct you, but this is a simple observation. I'm enjoying all of these videos, thank you very much for uploading them.
If you could figure out that this is supposed to mean the accusative, then it fulfilled its purpose well enough. Details like these doesn't really matter for grammar study, do they? It's like those students who suddenly can't solve algebra problems when you switch from using `x` to any other letter :q
That is what I was thinking. I'm not saying that there is a problem with writing/typing 'AKK' for 'ACC'. I can confirm that after 5 years of studying Latin, and having read numerous grammar books in English, that the accusative is indeed spelt with 'CC'. It's nothing serious, just a simple observation I made.
I would assume that, because his native language is German, he uses 'AKK' as an abbreviation for 'Akkusativ', perhaps by force of habit. I don't know if this is convention or not, we'll have to wait for clarification.
