New analysis of f116v, Central Bavarian dialect

[monisusa]

I would really like to see any 15th ct. reference for the letter „c“ used as an abbreviation of german „Zeh“ (toe). 
This may be some child‘s play with our language, but not all a usual speaking and writing — not even in some „Bavarian“…

Hello Stefan, thank you for your question. I agree, indeed it looks a little bit funny. It took quite some time, until I understood what the scribe wanted to express.
The point is not that "c" is a "usual" abbreviation for Zeh in German - it is that the scribe was not a native speaker of German and 
therefore did not follow usual German orthographic conventions. 
Apparently the author had no dedicated grapheme for the German /ts/ sound and when confronted with vernacular words containing this affricate, he used 
approximate spellings.  The reading is not hypothetical: it appears in two positions where the meaning "Zeh" is required by the recipe's semantics e.g.
an c hi ton (an Zeh hin tun - apply to toe ) and vals c nu z'vey so nim gasmich (if toe still too painful then take goatsmilk). A scribe with a foreign background might very well
use c to spell "Zeh".
Although the use of "c" for Zeh is unusual, it is entirely consistent with the orthographic habits of a non-native German scribe approximating unfamiliar sounds. A single text or
word only shows, HOW ONE person chose to spell a word. It is not automatically representative of the entire era. Apart from that, the orthography was not yet standardized at that time.
Kind regards, Monika
