Here's why:
* No Official Recognition: Pig Latin is a playful language game, not a language recognized by any government or official body.
* No Standardized Rules: While the basic rules of Pig Latin are generally understood, there are variations in how it's spoken and written. There's no official, universally agreed-upon set of rules.
* No Native Speakers: Unlike true languages, Pig Latin doesn't have native speakers or a history of being a primary language for a community.
Pig Latin is a fun way to play with language, but it remains a game rather than a legitimate language.
