Reconstruction:Proto-Slavic/kъňiga

Etymology
There are multiple theories:
 * Borrowed either from or from a different  source (compare 🇨🇬 and 🇨🇬).
 * From or, via 🇨🇬.
 * Ultimate Chinese origin, from (🇨🇬  < 🇨🇬, ), as paper was invented in China around the 1st century AD. However, this seems less likely due to the likely temporal precedence of Proto-Slavic over Early Middle Chinese and the large spatial separation of the donor and recipient languages.
 * Finally, Polish Slavicist Aleksander Brückner considers it to be a native word derived from Proto-Slavic *kъnъ (“trunk of a tree”) with the suffix -iga (compare Slovene veriga (“chain”), from Proto-Indo-European *wer- (“tie”)). The sense development would thus be similar to German Buch and English book, from Proto-Indo-European *bʰeh₂ǵos (“beech”), or to Latin liber, from earlier *luber, a cognate of Proto-Slavic *lubъ (“tree bark”).

The second and third theories require transmission by a or an  language, but nothing is attested in them. Although sometimes cited, 🇨🇬 and 🇨🇬, are both considered early Slavic loans. However, 🇨🇬 and 🇨🇬, which are unlikely to derive from Slavic, testify to the early presence of this word in the Volga region.
