Meaning & History
Si-u is a Korean unisex given name formed by combining Sino-Korean characters. The first syllable si (시) is derived from the hanja 始 (si), meaning "begin" or "start." The second syllable u (우) can be written with various hanja, most commonly 祐 (u), meaning "divine intervention" or "protection," or 雨 (u), meaning "rain." Other hanja combinations are also possible, allowing for a range of meanings. The name Si-woo is a variant form of Si-u. In South Korea, such Sino-Korean names are chosen not only for their phonetic appeal but also for the positive connotations of the constituent characters, reflecting values like new beginnings, blessing, or natural abundance.
