Maybe something like Eggcorns and other common grammatical errors. Same here. I think regular contributors to this thread know that the topic of "eggcorns" has evolved/ expanded into "other common grammatical errors". This can be a rare case of the more specific including the more general, rather than the more common case of the more general including the more specific!
