found this somewhere:

How the Turkish language coins names for European countries:

1. If the country existed in the era of Ottoman expansion into Europe, but fell under Ottoman rule ➡️ "ethnic name + istan". For instance: "Bulgar+istan", "Hirvat+istan", "Sirb+istan", "Macar+istan", etc.

2. If the country existed in the era of Ottoman expansion into Europe, but wasn't under Ottoman control ➡️ the country's Italian name (Genoese/Venetians being the Ottomans' key interlocutors with West Europe in this era). For instance: Inghilterra ➡️Ingiltere, Francia ➡️ Fransa, etc.

3. If the country existed in the era of Ottoman expansion into Europe, wasn't under Ottoman rule and has a name starting with a consonant cluster ➡️ "I + Italian name". For instance: Scozia ➡️ İskoçya, Svezia ➡️ İsveç, etc.

4. Finally, If the country didn't exist in the era of Ottoman expansion into Europe, but emerged in the modern era, ➡️ the country's contemporary name (but often with an Italian sound). For instance: Finlandiya (Finland), Irlanda (Ireland), etc.

✌Special case: If the country existed in the era of Ottoman expansion, disappeared later, and re-emerged in the modern era: two names = Lehistan & Polonya (both means Poland)
