Meaning & origin
Si is a minimal, unisex short name that has never charted in the U.S. top 1000. Recorded since 1927, its peak usage year was 2013, though it has never approached widespread popularity. The name's trajectory has remained stable over the decades, with no significant revival or decline. Si's appeal lies in its brevity and its connection to the more established names Simon and Silas, both of which have biblical origins. As a standalone given name, Si is a rare choice, reflecting the modern trend toward concise, nickname-style names.
Si is a diminutive of Simon or Silas. Simon derives from the Hebrew name Shimon, from the verb shamá (to hear). It appears in the New Testament as the original name of the apostle Peter. Silas is a Greek shortened form of the Aramaic name Seila, also related to Shimon. Si has been used as an independent given name in English-speaking countries since the 19th century, particularly in the United States where it was recorded as early as 1927.
