Quote:I'm pretty sure it is a double-t
Me too. But this duplication is probably the result of declension (as in the case with the now obsolete "hat").
This word is something with which one writes (supposedly on water). What can be used for writing?
But that's not that very important, after all...
I see two important would-be-clues here: these two strange shapes - one in the beginning and the other is the circular shape which looks pretty like the one in the end of VMS f116v.
"Tinte" is ink in German, maybe that's a spelling variant or just a scribal error. Writing with ink is natural. What is not natural is writing with ink on water... maybe "wag" stands for something else still
