Intended use for 'Meaning' and 'Description' in Lookups and Value Sets

Summary

What is each column/field intended for.

Hello,

In our Added Common Lookups, Custom Standard Lookups and Value Set values, there are two areas for configuration which appear on the UI when the end user is selecting a value.  

These areas are entitled 'Meaning' and 'Description' - the meaning seems to be the label for the user of the look up code which is clear, but I cannot find any documentation in terms of WHY the description appears on the front end, and how this can be utlised to add value to the end user experience.  I have seen it used for translations so as to have the EN in the 'meaning' and the other language in 'description' but I am quite sure this is not how Oracle intended it to be used.
