List of geographic terms attested in Hittite cuneiform texts.
Some names have multiple variants. With somewhat different suffixes. Some roots can create different toponyms. Like the wiyan meaning wine.
But the most important thing is the absence of such a term as Azzi-Hayasa or Hayasa-Azzi in cuneiform texts.
Both terms are separate with their own determinant URU. Forlanini do not use Hayasa-Azzi but mentions them separately claiming that Azzi was a different name for Hayasa introduced in Mursili 2 period. He treats them as synonyms of same kingdom.
They are other interesting toponyms there that I will discuss later.
