Quote:On the one hand we have situation, when gallow letters do not usually follow each other (for some unknown reason), but can follow each other.
On the other hand we have a glyph (y in the middle) which occurs almost always* near gallow.
Then the conclusion that y replace some gallow in certain situations is the simplest one. And it's f, I suppose.
Sorry, I still fail to understand the trail of logic here. In my opinion, it is the same thing as suggesting that (in a real language) if letter two follows (or precedes) letter one quite often, then letter two is a "replacement" for letter one.
If "H" frequently follows "T" in English language, and much less frequently follows any other character (space excluded), does that mean that "H" is a "replacement" for "T"? Surely not.
