Colletta is an uncommon Italian given name, derived from the Latin word 'collis,' meaning 'hill.' It's often considered a feminine form of Colin or Coleman. The name Colletta was likely popularized by Italian author Giovanni Verga, who featured a character named Colletta in his novel 'The House by the Medlar Tree.'
"Over the course of a century, from 1903 to 1978, the name Colletta experienced significant fluctuations in popularity.
