From Proto-Balto-Slavic *śárˀkāˀ. Cognate with Lithuanian šárka (“magpie”), Old Prussian sarke (“magpie”), Finnish harakka (“magpie”). Eventually connected with Russian со́рок (sórok, “forty”).
The original form was *sorka, with non-etymological *-v- in some daughters introduced by analogy from *svьrčati (“to whistle”), possibly in order to avoid confusion with the (reflex of the) verb *sьrati (“to defecate”).

* -asъ is the expected Balto-Slavic form but is found only in some Old Czech documents; -axъ is found everywhere else and is formed by analogy with other locative plurals in -xъ.
** The second form occurs in languages that contract early across /j/ (e.g. Czech), while the first form occurs in languages that do not (e.g. Russian).
Baltic cognates include Lithuanian šar̃kas, švar̃kas (“jacket, coat”), Latvian svā̀rks (“skirt”) (-v- possibly is influence of švarùs (“clean”))
