single-serving

The compound "single-serving" is a modern English formation that transparently combines two established words. "Single" traces back to the Latin singulus, which itself derives from the Proto-Indo-European root sem- (one), also the source for "simple" and "same." "Serving" originates from the Latin servire, meaning to be a slave or attendant, evolving through Old French to mean providing food or assistance. The logic of the compound is direct: a portion (serving) meant for one (single) person. In the late 20th century, its meaning expanded metaphorically, notably popularized by the film Fight Club, to describe transient, disposable items or brief, impersonal encounters, extending the concept of "for one use only" into social commentary.

Structure: single (one) + serving (portion) - single: From Latin singulus (one, individual, separate). Functions as an adjective meaning "one only" or "individual" in this compound. - serving: From the verb serve, via Old French servir from Latin servire (to be a slave, to serve). The suffix -ing forms a noun indicating the action or result of the verb. Here, it functions as a noun meaning "a portion of food."
