Syrus is a spelling of Cyrus, the Greek form of the Old Persian Kurush, a royal name of uncertain meaning that is traditionally explained as "sun" or "far-sighted". Cyrus the Great founded the Persian Empire and is praised in the Bible for freeing the Jews from Babylon; the y spelling gives the ancient name a modern edge. Syrus stood at number 1976 in 2015, peaked at number 1481 in 2023 and ranks 1820 in 2025.
