 Chak shares strong economic and social ties with Sukkur because of the natural geographic and trade route proximity.The word ‘Chak’ is said to be derived from a Sindhi language word ‘"chakki"’, meaning pot wheel, which is used to make pottery from clay.The clay used to be obtained from the ‘"cheeki matti"’, the mud from inside the nearby 'Kacha' area, which is the area between two levees of the Indus River bordering the town.
