machine-readable

The term is a modern English compound adjective, formed in the mid-20th century with the rise of computing. It logically combines three elements: 'machine', referring to the computer; the verb 'read', in its modern sense of interpreting symbols; and the suffix '-able', indicating capability. The construction follows a transparent pattern in English for creating technical descriptors, literally meaning "capable of being read by a machine." It directly reflects the need to distinguish data formats designed for automated processing from those intended solely for human interpretation.

Structure: machine (device) + read (interpret) + able (capable of) - machine: From Latin 'machina', via French, meaning a device or engine. In this compound, it functions as a noun modifier specifying the agent (the computer). - read: From Old English 'rǣdan', meaning to advise, interpret, or discern. In this compound, it functions as a verb root meaning to interpret data. - able: From Latin '-abilis', via Old French, a suffix forming adjectives meaning "capable of, fit for, or worthy of."
