interpretability

The word 'interpretability' is a modern formation built upon the classical Latin verb 'interpretari,' which meant to explain, translate, or construe meaning. The suffix '-abilis' was added to form the adjective 'interpretabilis,' meaning "able to be explained or understood." This adjective passed into English as 'interpretable.' Finally, the abstract noun-forming suffix '-ity,' from Latin '-itas,' was appended to create the noun denoting the state or quality of being interpretable. While the core concept of explanation is ancient, its specific application to the transparency of complex computational systems is a contemporary semantic development, illustrating how classical word-forming elements are repurposed for modern technical discourse.
