F66r question

[Koen G]

If you know the dialect, the whole sentence is crystal clear.

Ah, excellent. To me it's not clear yet, I have a few more questions.

1. In Germanic languages, the more specific part usually comes first, which is why we say "a red apple" and not "an apple red" (as one would in French). So why does it say "mush flour" and not "flour mush"? Wouldn't we expect a reverse word order, i.e. "melmuss"?
   
2. In "muss mel", the article is supposed to conform to "mel", since "muss mel" is a type of "mel". Since mel is neuter, we would expect the article das. Why is the article den or der? 
   
3. If it is all perfectly clear, why was the "m" corrected to "d"? This "d" is written like a mirrored "6", which is the same style used in the supposed article den/der. I would assume this correction to have been performed by the original writer, and not a Pellingesque parade of people mistakenly correcting the marginalia of others. So why was the m changed to d?
