Polskie baśka, rosyjskie башкá, ukraińskie бáшкá ‘głowa’ i ich etymologia w słowniku Maxa Vasmera
The three colloquial words for ‘head’ adduced in the title of this paper are of Turkic origin, cf. Tkc. baš ’head’. However, this author contests Max Vasmer’s opinion that the Russian word was borrowed from the Turkic dative form (baš.ka) with the meaning ‘per unit, each; pro Stück’. Moreover, it is suggested that the Ukrainian reflex continues, as a matter of fact, two words.
