Wiktionary:About Silesian

Silesian, also called Upper Silesian or Slavic Silesian (mainly in contrast to German Silesian) and natively called most popular as ślōnskŏ gŏdka (see also: Other native names), is a West Slavic language spoken in Upper Silesia (region within Poland and Czech Republic) and is nearly extinct around Namysłów and Syców in Lower Silesia. It's also spoken in a diaspora in Germany and Texas. Silesian is mostly classified as language, but some Polish linguists classify it as dialect of Polish language (mainly basing on sources from Polish People's Republic).

Other native names
The name ślōnskŏ gŏdka is the most popular native name of this language in public usage, but there is still a lot of another native names of this language: ślōnski jynzyk, ślōnskŏ mŏwa, ślōnskŏ rzecz, ślōnskŏ szpracha, ślōnske rzōndzynie and pō naszymu (which literally means: in ours/in our language)

Inheritence
Old Polish is given as the ancestor for Silesian, and in turn Proto-Slavic. Regular sound correspondences include:
 * 1) Old Polish long e -> y, except word finally
 * 2) long a -> o (might be long ō, ǒ, etc, depending on the position)
 * 3) initial o -> ô
 * 4) long o -> ō
 * on, oń, om -> ōN
 * 1) ą -> ōN, always -ōm word finally
 * 2) ę -> yN, ã word finally

Capital N stands for any assimilated nasal consonant.

Borrowings
Silesian borrowings can depend on the period in which they were borrowed. Before 1945 (including, for the most part with a few exceptions), preindustrial loans, German was the main donor language, and most international terms entered Silesian via German during this period. This includes mostly political and industrial terms. After 1945, Czech and Polish became the main donor languages, and for Eastern Cieszyn Silesia, this was solely Czech. Most modern, digital loans are via Polish.
