宾

Top indexing radical 宀 (roof) - guests are received under the host's roof. The roof radical anchors 宾 in the family of dwelling-related words: 客 (guest, also under 宀), 家 (home), 室 (room), 安 (peace). The roof signals 'in someone's house.'

Bottom component supplies the sound: bīng → bīn (just nasal-final shift). The simplified shape resembles 兵 but the etymological meaning came from traditional 賓, where the bottom was 貝 (cowrie/gift) - a visitor bearing tribute. The simplification kept the silhouette, lost the gift imagery.
