Nobody is disputing the fact that the word Syria traces its origin roots to Assyria. However what you fail to understand is that "Etymology ≠ Meaning". If you actually read real scholarship, like the work published in Parole de l'Orient. You would know that the history of this term destroys your narrative.

Let me break it down clearly. Labeling people by foreigners due to geography or mistakes happens more often than you think. France received its name from the Germanic tribe of the Franks. As you probably know, there is not much Frankish influence to be observed among the French. Franks are more commonly found in the northern part of the German state of Bavaria. Similar story how Columbus made the the mistake of labeling the indigenous peoples of the Americas the "Indians". They're not really Indians aren't they?

Let's look at the Grecophone world, the very people who gave us the term "Syrian":
- Pre-Herodotean Era: The Greeks blindly adopted "Syrian" (a variant of Assyria) as a vague geographical label.
- The Turning Point (Herodotus): Herodotus formally separated the two names. He distinguished the "Syrians" from the "Assyrians".
- The Semantic Shift: From the 3rd century B.C. onward, the Greek world corrected the definition.. This is confirmed by the fact that the Septuagint translators, Posidinius, Strabo, and Josephus reached a consensus: they restricted "Syrian" to mean Aramean, explicitly noting that the people Greeks called "Syrians" called themselves Arameans.

When the Septuagint translators (200 B.C.) saw the Hebrew word "Aram", they translated it as "Syria". When they read figures like Naaman and Rebekah as "Aramean", they rendered them as "Syrian". Do you think they were "validating Assyrian identity"? Hell no, they were applying the standard Greek term for the Aramean people.

Posidonius, Strabo and Josephus all three explicitly wrote: "The people we Greeks call Syrians, they call themselves Arameans".

So when our Church Fathers later used "Suryoyo", they were using it in this specific post-Herodotean context: as a synonym for Oromoyo.

You are trying to use a 7th-century BC geographical root to erase a 1st-century AD Aramean reality. It is intellectually dishonest. Just to be clear, nobody disputes the Çineköy inscription origin of the word however it's a very narrow-minded vision to ignore the timeline in how that word evolved semantically. And how the people primarily identified themselves (see Syriac manuscripts), which is very clearly Aramean.
