The Chinese word 一次性 is formed through a logical and common compound word structure, combining three morphemes: 一 (yī, meaning "one"), 次 (cì, meaning "time" or "occasion"), and 性 (xìng, a suffix meaning "nature" or "characteristic"). The core phrase 一次 creates the meaning "one time", and by adding the suffix 性, it nominalizes or adjectivizes the phrase to mean "the characteristic of being for one time/use only". Therefore, the entire compound semantically builds from "one" + "time/instance" + "nature" to arrive at its modern meanings of "disposable", "single-use", or "one-off".
