Meaning & origin

Sonni is a rare unisex name that first appeared in U.S. records in 1966. Although it never reached high popularity, it saw its peak usage in 1989, when it ranked 8,860th. Since 2013, the name has been rising in use, but it remains uncommon, with only about 1 in 146,115 children receiving the name in 2025. The name's origin is uncertain, likely a modern variant of Sonny, an English nickname for a young boy. As a spelling variant, Sonni lacks the historical depth of its root name but offers a distinctive option. It has not been consistently recorded in any top states, reflecting its scattered usage across the country.

Sonni likely originated as a variant spelling of Sonny, which is an English nickname derived from 'son' (Old English sunu), originally used to address a young boy. Its use as a given name emerged in the 20th century, particularly in the United States. The spelling Sonni may have been influenced by similar-sounding names or as a modern feminine variant.
