Bucak (nahiya) is the Turkish word for subdistrict, literally meaning "corner."
For example, in Konya Province (the province with the highest number of settlements), among the 31 districts, only 15 districts had bucaks, and the total number of bucaks was 23.
[2] Villages (Turkish: köy) are parts of the districts or bucaks.
Bucaks were important part of the Turkish administrative system prior to 1970, but since transportation facilities to villages were improved, the importance of bucaks declined.
(See Metropolitan municipalities in Turkey) With changes approved on 11 September 2014, all bucaks were abolished.
