I was holding this question back because I suspected that it wouldn't be objective enough, i.e. there wouldn't be a scale to classify the awfulness of grammar mistakes. Well, there is no such a scale, but thanks to this question, now I see that messing up with the articles is just a Kavaliersdelikt – for beginners at least. I think it would be useful to know which mistakes are particularly meant to be avoided. This question is, therefore, the other way around.
For instance I witnessed (so to say) the following dialog between a German learner (A) and a German (B):
– A: Dann Tschüß und so! Ich gehe nach Lidl. (somewhere apparently a mistake)
– B: Nach Lidl? Das klingt schrecklich! (verärgert)
The fact that I do lots of mistakes and never had seen a native speaker so exasperated because of them, together with the results of the question linked above, makes me suppose there exist indeed nails-on-a-chalkboard–mistakes.
Please classify the mistakes below. Which of them should the brain focus on, on the first places? I'll accept the most voted question.
forgetting the first part of the phrasal verb:
- Na, ich fahre jetzt (ab) oder
- Wenn…, kriege ich nichts davon (mit).
Die Sonne hat gescheint.
wrong auxiliary verb
- Ich bin deinen Geburtstag vergessen. Oder
- Erst jetzt hat das erschienen.
Ich gucke mir die WM-Finale zu Hause an.
wrong preposition (first example above)
wrong position of the verb
…, weil ich habe Hunger!
wrong declension: -e instead of -en in, say,
…die schöne Blumen.
- You might want to add those you think might be even more horrid.
