社交
shèjiāo · HSK 7
social interaction
🤝 社 society + 交 exchange = social interaction; people exchanging within a community
社 — 示 (altar/spirit) + 土 (earth)
Originally referred to the god of the soil and the altar where villagers worshipped it. The 示 component signals ritual or spirits, while 土 means earth, together evoking a community shrine. The meaning later broadened to 'community' and 'society'.
交 — top 亠 + 父-like crossed legs
Originally a pictograph of a person standing with legs crossed, showing the idea of crossing or intersecting. From this concrete image, the meaning extended to abstract senses like 'exchange,' 'interact,' and 'hand over.' Modern uses such as 交流 (exchange) and 交通 (traffic) all trace back to this core notion of crossing.
