DERA, a word of Persian extraction, has several connotations. The original Persian word derah or dirah means a tent, camp, abode, house or habitation. In current usage in rural Punjab, a farmhouse or a group of farmhouses built away from the village proper is called dera. Even after such an habitation develops into a separate village or a town, it may continue to be called dera, e.g. Dera Bassi in Patiala district of the Punjab, or Dera Ghazi Khan and Dera Isma`il Khan in Pakistan. Where colloquially used in place of Hindi dehara, the word will carry the connotation of a temple or memorial over a cremation site.
