Template:Acronym/LongName
From Halopedia, the Halo wiki
Usage
This template converts one of Halopedia's two-to-six character long acronyms into the full name of the topic that corresponds to the acronym. For instance, {{Acronym/ToPage|CE}} produces "Template:Acronym/ToPage".
However, be warned: what this template returns is not guaranteed to be a valid page name on Halopedia! If you're looking to link to a page using an acronym, the template you're looking for is Template:Acronym/ToPage!
