The Chinese word **地铁站** (dìtiě zhàn), meaning "subway station," is a logical compound formed by combining three distinct morphemes: **地** (dì, "ground/earth"), **铁** (tiě, "iron"), and **站** (zhàn, "station"). It is structured as a modifier-head phrase where **地铁** ("subway," literally "ground iron," referring to the iron railway underground) acts as an attributive modifier to specify the type of **站** ("station"). Thus, the term directly and transparently denotes a "station for the underground railway."
