Jaska

Jaska is a Finnish masculine given name that originated as a colloquial diminutive of Jaakko, the Finnish form of Jacob, which itself traces back to the Hebrew name Ya'aqov, meaning "supplanter" or "one who follows at the heel." The name developed within Finnish vernacular tradition as an affectionate short form and has long been associated with everyday Finnish culture. Related forms include Jaakko, Jukka, and the broader family of Jacob-derived names such as Jakob, Jacques, and James.
