words in the leaves of ms LJS419 f18r

[MarcoP]

It does not look to me that all words are the same. Unfortunately, only "uon" is readable.

What if each leave contains only part of the word or a phrase?

I agree; that is a possibility.
It seems to me that the other words are also made of three letters, with something more or less circular at the center. But they are very blurred, so it's hard to tell.

Even considering "uon-" as the prefix of a six letters word, I cannot think of a possible meaning.
