A modern two-character given name combining
吉 (jí, 'auspicious') and
宇 (yǔ, 'universe / cosmos').
宇 became fashionable in 21st-century baby naming for boys — pairs like
子宇,
浩宇,
吉宇 sound contemporary and ambitious without straying into the rare-character territory. Names with
宇 evoke openness and breadth.
