Crimean Tatar language
The name "Taphros" in Greek means a dug-out trench, per a defensive trench dug between the Azov sea and the Black sea; there also appears to have been a town in the vicinity of the same name. The Crimean Tatar name of "Or Qapı" adopts the Greek in the Crimean Tatar language meaning "Or"=trench and "Qapı"=gate, and "Perekop" in the Slavic languages literally means a dug-out.
