No text, but a visual code

[-JKP-]

...

  You can see Eva-k as abbreviation in radices and capitis. Does it do the same function in both? I don't think so.



The glyph is the same for radix and radices, which suggests that it does not have a grammatical function....

The abbreviation is based on sound. It's the "-is" abbreviation, and it can stand for anything that sounds somewhat like "is", which means it can stand for "-ix" or "-is" or sometimes "-es". It can also be used for "-em" as in "Item" (very common).

As long as it's close and it's clear by context, it can be used. Most Latin abbreviation symbols are like that.
