Tüfekçi (Pontic: Αρσέλα) is a neighbourhood of the municipality and district of Dernekpazarı, Trabzon Province, Turkey.
[2] "Tüfekçi" literally means "riflemen" or "gunsmith" in Turkish, evidently referring to the profession of at least some early inhabitants of the village.
Perhaps coincidentally, a village named Arşela existed on the west coast of the Black Sea.
Ivan Duridanov has claimed that the river names Arsio, Arse in Old Prussia, Arsen and Arsia in Latvia and Arsina in Germany are derivation of the root ors-, ers “(for water) flow, damp” in the Indo-European language family (Hindi arşati) and ars- in the Thracian language.
He connected these words to place names such as Arsa, Arsaza, Arsena, Arsila in Dacia (an ancient region in Romania covering territories north and west of Arsela) (Duridanov, 1976).
