Meaning & origin
Sydni is a modern spelling variant of Sydney that emerged in the late 20th century, first recorded in U.S. data in 1947. The name reached its peak popularity in the year 2000, but has since been declining in use. In the most recent year, 2025, Sydni ranked #10,917 and was given to approximately 1 in every 200,908 newborn girls. The spelling variant Sydni is much less common than the standard Sydney, and it has not been recorded in the top 1,000 names since the early 2000s. The name is typically given to girls, reflecting the broader trend of Sydney and its variants shifting toward feminine usage. While not widely used in any particular state, Sydni has a contemporary feel and is often chosen by parents seeking a unique spelling of a familiar name.
Sydni is a modern spelling variant of Sydney, which began as an English surname derived from a place name. The place name Sydney has Old English roots from 'sīd' (wide) and 'ēa' (river) or 'īeg' (island), meaning 'wide island' or 'wide riverbank'. The name gained popularity as a given name in the late 20th century, largely due to the unisex appeal of Sydney, and Sydni emerged as a distinct spelling variant particularly used for girls.
