Chak is an Urdu word, which means village. In the Punjab province of Pakistan, numbers are using instead of names. The villages are named using a certain nomenclature that dates back to British Rule, all names are prefixed "Chak" followed by a number and a letter. The number is the name of the village and the letter indicates how much water the village uses.
