Mondo is of Italian origin, meaning 'of the world' or 'universal'. It gained popularity as a given name during the mid-20th century and was often used by parents seeking unique, non-traditional names for their children. Mondo is gender-neutral but has been more commonly used for males. In Italy, it's associated with intellectuals and artists, such as Italian film director Federico Fellini, who named his son Mondo.
"The name Mondo experienced fluctuations in popularity over time, with peaks in the late '60s to mid '70s and again in early 2000s."
