köken: From earlier -han, -hVn (now dialectal), from Proto-Finnic *-hën, *-sën (passive or reflexive suffix), the same as the third-person singular possessive suffix (see the possessive suffix entry on -Vn). Initial -ta- is from the passive marker *-tta-.
From Proto-Albanian *ana, from Proto-Indo-European *h₂enō (“along a slanted surface, etc.”), from *h₂én (“on, upon, onto, up to”). Cognate to Ancient Greek ἀνά (aná, “on, upwards, along”), Gothic 𐌰𐌽𐌰 (ana, “on, in, against, because of, about”), English on, and Old Prussian no, na (“on (where), against, about there”).
