Meaning & origin

Coni is a rare respelling of the nickname Connie, itself a diminutive of Constance. First recorded in the U.S. in 1943, its peak year was 1961, but it has never ranked among the top 1000 names. The name has remained stable in usage since the 1960s, with very few births each year. Coni offers a simple, modern twist on a classic nickname, appealing to parents seeking a concise yet distinctive choice.

Coni is a diminutive or variant spelling of Connie, itself a pet form of Constance. Constance derives from the Latin constantia, meaning steadfastness or constancy. The name has been used in English-speaking countries since the Middle Ages, with the nickname Connie becoming common in the 19th century. Coni represents a modern respelling that gained some use in the mid-20th century.
