KAUR
Kaur is an integral part (second half) of the name of a Sikh female. Without using this, a female cannot claim to be a Sikh, because Kaur is not a suffix for a Sikh female but it is, in fact, a part of her full name.
Kaur means prince (and not princess). A Sikh girl is supposed to be as brave, responsible and important as a male prince is. This symbolizes equality of women and men in Sikhism. It also symbolizes Sikh national cohesion.
