Bizanc, obviously from Byzantium, correct?

Well no, the city itself was always greek populated

The suburbs were slavic, as most of the greek cities

True that.

Well the slovenes usually transfrom the unessesary suffix -(ti)um into ec

Hm, nice.

Let's see, for example

Ptuj was converted into Poetoio I believe

Since latin pronounciations

Makes sense.

Like let's look at mainland Turkey place names

Izmir

With the suffix -mir

Meaning "peace"

Literally meaning "from peace"

Or "Myrna" >Mirna directly meaning "quiet or peaceful town (female)"

I’m aware that a lot of a lot of the current Turkish cities/regions sound similar to how they did when they were Greek, like Konstantinyye was Constantinople (before it was renamed Istanbul), Konya was Iconium, Trabzon was Trebizond/Trapezium, and a few more.

I'm pretty sure if you give me old place names in all of europe I'd be able to pull out a slavic meaning

Uh

St. Petersburg

Petrograd

Peter's burg

Simple as that

🅱etersburg

Or Leningrad back during the Soviet times, obviously meaning City of Lenin.

oh no

Renames

How about... Sevastopol.

Grad actually means "castle" or building area

We just have a tradition of calling cities as "castles"

But we still use "place" as town

Like west slavs do

The south slavs use grad as both castle and city

Sevastopol by the apperance is totally greek

You see the pol

Right.

/sevastopol/

I don't know the polis of sevas?

Next, Warsaw.

Varšava

Female city name
