Here are three of the four Thracian inscriptions. I translated two of them differently from the official translations, and of course there’s a lot I’m assuming. Question marks show stuff I’m really not sure about. What do you think?
SEG 45:835

dal/del < PIE *delh₁-? = protect < share < divide
-e < PIE *-dʰi? = 2nd person singular imperative
me < PIE *h₁mé = 1st person accusative pronoun
The golden ring of Duvanli

Raw text: ΡΟΛΙΣΤΕΝΕΑΣ NΕΡΕΝΕΑ ΤΙΛΤΕΑΝ ΗΣΚΟ ΑΡΑΣ ΖΕΑ ΔΟΜΕΑΝ ΤΙΛΕΖΥΠΤΑ ΜΙΗ / ΕΡΑ ΖΗΛΤΑ
Transliteration: Rolisteneas Nerenea tiltean ēsko aras zea domean Tilezupta miē era zēlta.
Translation: I am Rolisteneas, a descendant of Nereneas. Tilezipta, an Arazian woman, delivered me to the ground.
My translation: I am Rolisteneas, a descendant of Nereneas. Tilezypta, master of Araszeas, comes to me (with) gold.
Gloss: Rolisteneas Nereneas.dat descendant.acc 1st.nom Araszeas.dat master.acc Tilezypta 1st.dat come.3rd gold.
Rolisteneas = male name
-eas < *-o-s = singular nominative masculine
Nereneas = male name
-ea < PIE *-ey = singular dative/genitive masculine (the merger of the dative and genitive is a feature of the Balkan sprachbund, and I’m assuming Thracian had it too)
tilteas < PIE *dʰelh₁- = descendant, scion
-ean < PIE *-o-m = singular accusative masculine
ēsko < PIE *h₁eǵ(oH) = 1st person nominative pronoun

I can give Greek and Albanian cognates if you want them.
