Dear LOTUS, as per my understanding the word "Sikh" in derived from Sinh (lion). Every male sikh is called a "Singh" (Lion) and every female is called "Kaur" (princess) in Sikh tradition.
Sikh religion is considered as part of Hinduism (except by a few die hard sikhs who claim that their is a separate religion - this trend started about 30 years back or so only). The late Master Tara Singh was one of the founding memebr of VHP (Vishwa Hindu Parishad). Many hindu families make their first born child as a "Kershdhari sikh" and also marriages between sikhs and hindus are common among the Punjabis.
