Hmm, I seem to be unmethodical in my German learning ... why not start at the beginning? Here is the vocabulary that I don't already know for the first Harry Potter, up to chapter 6. What seems to work fairly well now, is I watch sections of the movie three different ways. I first watch with English speech but subtitles with German for the hearing impaired. I pause frequently to scan for words I don't know, and to test if I understand what I am reading. I suppose this is similar to German speech and English subtitles, but in that I know instantly what word is being used. Then I watch two more times with German speech, one with German subtitles, and then without.
One thing I find, when scanning the German subtitles for the first time, is that even if I am familiar with all the words, the word order or grammar baffles me, and I have no idea of the meaning of the phrase. This is after having some instruction so I know basic sentence construction. These are presumably more specific constructions, or colloquial phrases. I have not made note of these here, but perhaps I will in the future.
And as an example of how the English construction does not transfer to German construction, here is what Dudley's English mother says on his birthday, "I want everything to be special on my Dudley's special day". Dudley's German mother says instead (directly translated) "I want, that everything is perfect, when my Dudley has his special day". More verbs in the German one. And somehow, the Germans split up complex sentences into prepositional phrases automatically.
