köken: Produced by dissimilation of earlier *кочерга́р (*kočergár), from кочерга́ (kočergá). For the р falling compare гонча́р (gončár) < гърньчаръ (gŭrnĭčarŭ). Compare typologically English stoker (“a person who stokes; a poker”). Note the French counterpart chauffeur, from which many descendants arise, including шофёр (šofjór).
