at-risk

The compound adjective "at-risk" is a relatively modern formation, emerging in the mid-20th century from the common English prepositional phrase "at risk." The preposition "at," with its Old English roots, establishes a state or condition. It is combined with the noun "risk," which entered English via French and Italian, tracing back to a post-classical Latin source associated with peril at sea. The logic of the term is transparent and literal: to be positioned "at" the state or condition of "risk." Its specialized application in social, educational, and medical contexts to describe vulnerable populations represents a semantic narrowing of this core idea, formalizing a colloquial phrase into a standard classificatory term.

Structure: at (preposition) + risk (noun) - at: Old English origin, a preposition indicating location, state, or condition. - risk: Mid-17th century, from French 'risque', from Italian 'risco', likely from a Vulgar Latin verb meaning "to run into danger".
