Something that is easy to read or understand, often because of its clear style or format.

Readable → It is formed from "read" (from Old English *rædan*, meaning to interpret or understand) and "-able" (meaning capable of). The word "readable" means capable of being read or easily understood.
Think of the ability to 'interpret' ('read') something, and the suffix '-able' means it can be done. So, something that is readable is something you can easily interpret.
