Never mind. "Sacrie" could also be a German toponym (it's difficult to tell sometimes because Austrian authorities used both Italian and German in this area, but the "Z" becoming "S" is an indicator), I've put it under "old_name:de"

Hi, sorry for answering three years later, but I saw your comment only now. I've fixed it, "Sacrie" is the old historical Italian toponym that can be found in old documents from the Austrian empire-era, while "Zacrie" was the Italianized version of the Slovenian name adopted by Italian (fascist) authorities in 1923, that was the official name until 1947 when the area was annexed by Yugoslavia after the peace treaty.

There was consensus here https://community.openstreetmap.org/t/old-italian-and-german-toponyms-in-slovenia/102062/25 about the fact that the toponyms not used anymore in italian language should be moved to old_name:it or deleted. Please discuss there or stop your reverts.
