The name "Kaur" is of Punjabi origin and is commonly used as a surname for Sikh women. In the Sikh tradition, "Kaur" means "princess" or "lioness," symbolizing strength, dignity, and royalty. It was adopted by Guru Gobind Singh, the tenth Sikh Guru, to ensure that all Sikh women would have a surname that reflected their equality, strength, and noble status, regardless of their family background.
