Creates a version of Module:etymology languages/data in which there is just one code per language. Codes that have the same language data are reduced to the most language-codiest one. For instance, Austrian German has three codes (Austrian German, AG., de-AT) by which it can be accessed in etymology templates like {{cog}}. de-AT is chosen as the only language code for Austrian German because it looks the most like a language code.
The following criteria are used successively to weed out candidates for language-codiest code:
This list shows those etymology languages that have multiple codes, together with the code chosen by this module and the other codes:
