Lulu لؤلؤة comes from the Arabic word meaning “pearl” and is often used a female given name. I’ve also come across the name as being used as a pet-name often given to slaves (male and female) in the ancient Middle East.
Lulu also originated as a diminutive of names beginning with the Lu/Lou sounds such as Louise/Louisa (“famous battle” or “famous in battle”), Lucy, Lucia (“light”), Luanne (a combination of Louise + Anne “favor, grace”), etc.
Lulu is also a Chinese female name, often used as a double name such as lù lù 露露 meaning “dew” or lù lù 璐璐 “beautiful jade”. There are likely other meanings depending on the characters used.
