Chelli is of Italian origin, derived from the Latin 'Caecilia,' which means 'blind.' It is often associated with Saint Cecilia, a martyr venerated by both Catholics and Orthodox Christians. The name gained popularity during the Middle Ages due to her widespread veneration. Chelli is typically used as a female given name but can also be found as a surname in some regions.
