Where did the word audible come from?

The word "audible" comes from the Latin word "audibilis", which is the past participle of "audire", meaning "to hear".

Here's how it evolved:

1. Latin: *audibilis* (meaning "able to be heard")

2. Middle English: *audible* (adopted from Latin)

3. Modern English: *audible*

The word "audible" has been used in English since the 14th century, making it a relatively old word in the English language.
