Tooltip - more dynamic

[Lindsey]

I have been looking for a way to hover over a word in my company's Confluence space that would then define the term. The idea is to ensure everyone understands this word to mean the same thing (lots of 'jargon' in our industry, leaves ample room for miscommunication). 

In searching, I found the Macro "Tooltip", which is close, but it requires adding them individually.

I am looking for something which would ping a created "dictionary". So a "tooltip" in the functionality of information display, but you only have to maintain 1 area instead of lots of different tooltips. 

Example: "PRN" is added and defined in a single location. Now, everywhere in our company's confluence space "PRN" is referenced, a hover-over appears defining the word.
