köken: Borrowed from Latin Iōāchīmus, from Ancient Greek Ἰωακείμ (Iōakeím), Ἰωακίμ (Iōakím) (2 Kings 24), from Biblical Hebrew יְהוֹיָקִים (yəhôyâqîm, literally “may Yahweh raise up”).
Karelian form of Russian Яким (Jakim). The municipality was presumably originally named Jaakkimanvaara (with vaara (“(large, forested) hill”)). Folk etymology derives the name of the municipality from Jacob De la Gardie, but (a variant of) the name is already attested when he was just a child, making this anachronistic.
