'audible' originates from Latin, specifically the word 'audibilis', where 'audire' meant 'to hear'.

'audible' came into English via Old French and Middle English from Latin 'audibilis' (from 'audire'), eventually becoming the modern English word 'audible'.

Initially it meant 'that can be heard' (from Latin), and this basic sense has remained; later it gained related senses such as a spoken 'signal' in sports contexts.
