 Georgian scripts are unique in their appearance and their exact origin has never been established ; however , in strictly structural terms , their <unk> order largely corresponds to the Greek alphabet , with the exception of letters denoting uniquely Georgian sounds , which are grouped at the end . Originally consisting of 38 letters , Georgian is presently written in a 33 @-@ letter alphabet , as five letters are currently obsolete in that language . The number of Georgian letters used in other Kartvelian languages varies . The Mingrelian language uses 36 , 33 of which are current Georgian letters , one obsolete Georgian letter , and two additional letters specific to Mingrelian and Svan . That same obsolete letter , plus a letter borrowed from Greek ( making 35 letters total ) , are used in writing the Laz language . The fourth Kartvelian language , Svan , is not commonly written , but when it is , it uses Georgian letters as utilized in Mingrelian , with an additional obsolete Georgian letter and sometimes supplemented by <unk> for its many vowels .
