Sikhs have a given name and one or both of a surname and a Khalsa name. The surname may be a family name (based on the name of the ancestral village) or a caste name. Different castes still exist today in some aspects of Punjabi culture; similarly to the Hindu caste system, this system is based on employment (ex. jatt signifies the farming caste). On becoming a Khalsa, the Sikh undertakes the obligation to wear the physical symbols of this status (the Five Ks) and takes the name "lion", usually romanized as Singh, if a man, or /kaur/ "the Crown Princess" for female, usually romanized as Kaur, if a woman. (Note that Singh is spelled irregularly: it is written /singh/ but pronounced /siṅg) These names reflect the strong egalitarianism of the Sikh religion. The adopting of the Khalsa name is symbolic for being a member of a larger family or faith. These names were originally intended to replace the Sikh's original surname, which was often a caste name. Some Sikhs do replace their original surname with their Khalsa name, but many retain their original surname and add the Khalsa name before it. Thus, a man born Sandeep Brar should become Sandeep Singh but more likely will become Sandeep Singh Brar. Similarly, a woman born Harjeet Gill should become Harjeet Kaur or Harjeet Kaur Gill. First Names Sikhs use a set of several hundred given names, all or nearly all meaningful, usually with a religious or moral theme. For example, Ujjal means "bright, clean, holy". The process of choosing a Sikh's first name, known as the Naam Karan, occurs following the first few days of their birth, in a ceremony called the Hukamnama (referring to a hymn from the Guru Granth Sahib as the will from God); a family often selects a name for a child by opening the Sikh holy scripture, the Guru Granth Sahib to a certain "aang" and choosing a name that begins with the first letter of the first word on the "aang". Sikh given names are gender neutral, generally formed of a prefix and a suffix (ex. Har/jeet/). There is however, a gender connotation attached when pronouncing a name, say Parkāśh for example; it may be either male or female, but /parakāśō/ is female while /parakāśū/ is male. Last Names In Sikhism, women don't change their surnames after marriage - this is due to the fact
