interpretable

The word 'interpretable' is a modern English formation built upon the established verb 'interpret'. The verb itself originates from the Latin interpretari, meaning to act as an intermediary, explain, or translate, which is derived from interpres, an agent noun for a broker or explainer. The suffix '-able', of Latin origin via French, is productively attached to verbs to create adjectives denoting a passive capacity. Thus, the literal construction "capable of being interpreted" directly and logically yields the modern abstract meaning of something that can be explained, understood, or assigned meaning.

Structure: interpret + able - interpret: From Latin interpretari (to explain, translate, understand), via Old French. The functional role is the core verb meaning "to explain or understand the meaning of." - able: From Latin -abilis (capable of, fit for), via Old French -able. The functional role is a suffix forming adjectives meaning "capable of being [verb]ed."
