f69v_f70r1_f70r2 - Strange Voynich (Latin?)

[nablator]

I was looking on my phone, so I may have missed the two dots. So would the 9 with macron be kind of a redundant way to write something like "con"?

Yes the macron would be totally redundant. The most common uses of the "9" abbreviation are con/com, -us, -ost ("p9" = post). "Contra" would be typically abbreviated as "9t~" = con+t+ra. Lots of rare variants though: You are not allowed to view links. Register or Login to view. The important information that is missing in Cappelli is the frequency. Most listed abbreviations are rare or were no longer used by the 15th century. 

What ChatGPT says from its total lack of knowledge on the subject of 9+macron is wrong. If it exists at all in a Latin ms. its meaning would be unclear.
