The term "世贸" is a condensed compound word formed through abbreviation, where "世" is taken from "世界" (shìjiè, meaning "world") and "贸" from "贸易" (màoyì, meaning "trade"), combining to create the meaning "world trade." This is a common method of word formation in modern Chinese, creating efficient and widely recognized terms, most famously used as the shorthand for the "世界贸易组织" (World Trade Organization, WTO).
