Jaleen is of American origin, derived from the French 'Jacques', meaning 'supplanter'. It was brought to America by French settlers and has since become a unique unisex name in the United States. The name gained popularity in the late 20th century and remains relatively uncommon today, making it an appealing choice for parents seeking distinctive names for their children. Its pronunciation is often /jəˈliːn/ or /dʒəˈliːn/, with a soft 'j' sound followed by two syllables of equal stress.
"Jaleen has seen a significant increase in popularity since the late 1990s, with peaks in the early 2000s and again in 2005. However, it remains relatively uncommon overall."
