History & Origin

The English word sincere comes from Latin sincerus, meaning 'whole,' 'genuine,' or 'clean.' Roman writers used it to describe wine unmixed with water and reputations untainted by falsehood. Its use as a given name is a modern American development in the tradition of virtue names.

Sincere emerged as a given name in the United States in the late 20th century, reflecting a broader movement toward virtue and word names, especially in African American communities. It carries a positive declaration of character. Rapper Sincere has helped keep it in popular consciousness.
