actionable

The word 'actionable' is a modern English formation built upon the well-established noun 'action,' which itself descends from Latin āctiōnem, the noun of action from the verb agere (to drive, do, act). The suffix '-able,' of Latin origin via Old French, was appended to create an adjective meaning "capable of being acted upon." In legal contexts, this evolved specifically to describe a situation or wrong that provides sufficient grounds for initiating a lawsuit, thus shifting from a general sense of "doable" to a precise term meaning "liable to a legal action." This semantic specialization illustrates how English adapts classical elements to serve specific professional and practical needs.
