The Polish orthography system was used while writing texts in 18th and 19th c. Latgalian texts were written using the Roman type – the type was a factor distinguishing Latgalian texts from Latvian ones (Nau 2011: 5Nau 2011 / komentarz/comment/r /

).

Latgalian has a spelling standard, but not everyone accepts it. There is discord between principles proposed by specialists and habits of users without linguistic education: the standard does not reflect full scope of traditional elements of spoken Latgalian.
