The Naming of Kingdoms

Here is a chance to help out with the ongoing creation and development of a campaign world.

Most of the time it seems like you can just slap a name on a kingdom and you're done. Many times it seems unimportant to know the name of the kingdom, if your PCs are mainly dealing with one large town and the surrounding area. But in my world, that simply isn't so.

When I made this world, I pretty much populated it in a storm of creativity, scribbled down kingdom boundaries, and came up with names on the fly.
So I have fun place names like Acharya, and Scharnhoff. Inhabited by Acharyan elves, and Scharnovian dwarves. My point here is, see how the kingdom name lends itself to a nice, pronounceable suffix? Yeah. That's nice. England, with the English, Japan with the Japanese, right? Shouldn't be too hard to put these suffixes in place...! Or so I thought.

Then I started going over the names again.
So. Here's my list. You'll quickly see what the problem is. Parenthetical comments are pretty much there for emphasis.

Ladmirault - Ladmirans
Borqu - Borqese? Borqans? (pronounced Borkan?!)
Zokaras - Zokarans
Middelvede - Middelvans? augh
Khadijah - Khadish, Khadi
Scharnhoff - Scharnovian
Akdemir - Akdemiran
Zaldana - Zaldanan
Sulimen - Suli, Sulimese
Plains of Suhl - not really a kingdom, does it need a suffix?
Zara - Zaran (defunct in certain time settings, as this kingdom was absorbed Yr 475)
Malveaux - Malveran (also defunct, as this kingdom fell in Yr 468 or so)
Zamarna - Zamarran, Zamarnan
Bharat - Bharati
Delcina - Delcinian, Delcese, Delcinan (lame)
Mikish - Mikish, Mikash, Mikishese? (augh)
Serna - Sernese, Sernan (lame)
Mancera - Manceran
Sangani - Sanganese
Suddoth - Suddan, Suddothese, Suddokite? (lame)
Zandiphal - Zandiphalian, Zandiphite
Malivar - Malivaran, Malivite, Malivarish?
Acharya - Acharyan
Morvant - Morvannish, Morvanite, Morvanian (also, time consideration, this land fell in Yr 496)
Adeghani - Adelghanite, Adelese?, Adelghanish, Ghanese

Yeah.
Any commentary or thoughts would be helpful.
