The IAU catalogue's account
From the Turkish word yildiz, "star." In Early Modern times this common noun was erroneously said to be a Turkish name for the Pole Star (α UMi). Misspelled as "Yildun," the word was arbitrarily applied as a star name to δ UMi in recent times.

Layer of tradition and ancient-layer signal are not the dictionary authors' judgement but a keyword reading of the entry's wording. “No simple cue found” means exactly that — the parser found none — not that the name is late.
