Seon-u is a Korean given name that can be formed from various Sino-Korean hanja characters. Common combinations include seon meaning "good, virtuous" (善) or "declare, announce" (宣) plus u meaning "house, universe" (宇) or "help, protect" (佑). This morphological flexibility means Seon-u belongs to a larger set of related names sharing the same possible hanja and/or similar pronunciation. As with many Korean given names, Seon-u is typically two syllables, with each syllable corresponding to a meaning-bearing character. The first element, seon, frequently appears in Korean names with benevolent meanings, while u can connote concepts like the cosmos or blessing. Although Seon-u is used across South Korea, its exact usage by gender is ambiguous: though often male, some instances may be genuinely unisex. A closely related variant is Sun-woo, which differs slightly in the romanization but can use many of the same hanja combinations. Among famous bearers of the related form Sun-woo is actor Sun-woo Eun-sook, but Seon-u itself ‐ as a spelling ‐ may be less common. Meaning: Possible interpretations include “good universe,” “declaring benefits,” and other combinations depending on chosen hanja Origin: Sino-Korean Type: Normally first name (given name); may be used for any gender Related names: Sun-woo (variant romanization)
