audible

The word "audible" is a direct borrowing from the Late Latin term audībilis, which itself is derived from the classical Latin verb audīre, "to hear". The suffix -ibilis is a productive adjectival ending in Latin, creating the meaning "able to be heard". This logical construction passed into Middle English via Old French, retaining its precise semantic link. The core root aud- can be traced further back to the Proto-Indo-European root h₂ew-, meaning "to perceive" or "to be aware of", which also gave rise to words like "audience" and "audio", consistently relating to the faculty of hearing.
