Proto-Slavic

Etymology

From Proto-Balto-Slavic *śauˀ-. Cognate with Lithuanian šáuti (“to shoot, to shove”) (1sg. šáuju, šóviau), Latvian šaũt (“to shoot, to shove”) (1sg. šaũju, šaũnu, šãvu), East Latvian dialectal saũt (“to shoot, to shove”).

Per Derksen, no clear cognates outside of Balto-Slavic.
Per Vasmer, potentially cognate with Gothic 𐍃𐌺𐌴𐍅𐌾𐌰𐌽 (skēwjan, “to wander, to walk”), as well as Old High German sciozzan (“to shoot”), Old Norse skjóta (“to shoot, to move, to push”), Old English sċēotan (“to shoot”), English shoot, Albanian heth (“to throw, to winnow (grain)”) (aorist hodha).
Per Trubachev, cognate with Hittite (šuu̯āi-, “to push, to move”), Sanskrit सुवति (suvati, “to set in motion”) (although this precludes any connection with the above Balto-Slavic and other cognates, and assumes underlying Proto-Indo-European *s- rather than *ḱ-).
