Latgalian (<- correct spelling) is a dialect spoken by maybe tens of thousands of people in the province of Latgale. I assumed that since this was a distro from Latvia, that I was looking at Latvian when I booted it up. I did not take the hint that "Austrumi" was referring to the east of Latvia, which is the province of Latgale.

I might have had a better chance understanding spoken Latgalian. Written Latvian is all phonetic, having been designed by 15th c. German clergy to teach us barbarians a proper religion without burdening us with difficult spelling rules. Written Latgalian is a retrofit.
