UNUSUAL OTTOMAN IVORY YATAGHAN TRANSLATION PLEASE

[Zifir]

I think we are not looking at a standard Muslim or Turkish name. Just an opinion but this might be a non-Muslim name or a nickname. There are possible combinations but nothing exact. It might be:

a(e)-h- a(e) -l - i

or with a little bit overstretching it can be read as adalı (meaning "from island") and might be a nickname.

Best,
