Here's why:
* No native speakers: Pig Latin doesn't have any native speakers. It's a game played by English speakers.
* Limited vocabulary and grammar: Pig Latin uses the rules of English, just with some modifications. It doesn't have its own distinct grammar or a set vocabulary.
* Not a communication system: Pig Latin is a game played for fun and entertainment, not a system for communicating complex thoughts or ideas.
So, to answer your question, Pig Latin is not a dead language because it was never a language to begin with.
