 In a 2016 research in Turkey by KONDA Research and Consultancy, 0.01% of respondents claimed their native language to be Coptic (possibly confusing the words "kiptıce" (Coptic language) and "kipçak" (Kipchak).Coptic uses a writing system almost wholly derived from the Greek alphabet, with the addition of a number of letters that have their origins in Demotic Egyptian.This is comparable to the Latin-based Icelandic alphabet, which includes the runic letter thorn.
