Harleen, of Sanskrit origin, translates to 'second' or 'junior', implying a sequel or continuation. It's composed of two elements: 'hara', meaning 'next', and 'lina', signifying 'lineage'. This name has been popularized by the comic book character Harley Quinn from DC Comics, but its roots lie in ancient Sanskrit nomenclature.
"The name Harleen experienced significant growth in popularity starting around the year 2000, with a notable spike from 27 births in 2001 to 31 births in 2002 and reaching a peak of 97 births in 2015. However, it has since declined, with only 42 births recorded in 2023."
