Meaning & origin

Cincere is a modern invention that first entered U.S. birth records in 1999, a time when newly coined names with unconventional spellings were gaining traction. Its meaning is transparent, drawn directly from the English word 'sincere', though the deliberate misspelling distinguishes it from the traditional virtue name Sincere. The name reached its highest rank of 4050 in 2025, with a peak in absolute usage in 2023. Its trajectory has been stable, suggesting a small but consistent group of parents choosing it each year. While no U.S. state recorded enough instances to be listed as a top state for Cincere, it appears to be a rare choice nationwide, appealing to those who value phonetic spelling and a straightforward positive meaning.

Cincere is a modern invented name, formed from the English word 'sincere' meaning honest and genuine. The spelling change from 'sincere' to 'cincere' is a common respelling trend, possibly influenced by names like Cinderella or the prefix 'cin-' seen in names like Cinco. It first appeared in U.S. birth records in 1999, reflecting a pattern of adopting virtue names with modern spellings.
