"Apostryphal Grammatical Constructions"

I think that "apostryphal" really ought to be a valid adjective. That seems like a great way to discuss apostrophes, especially when they annoy me or I want to change them.

Based on my quick googling, however, this appears to be apocryphal.

I also like the idea of evoking apocalypses in related comments and puns.

Example usage: "I rewrote the sentence to avoid apostryphal grammar."
