@yvanspijk I've been enjoying your language infographics!
Here's a puzzler: do you have any idea where the pronunciation in some US English accents of the word "across" as "acrost" comes from? As in "I haven't come acrost that before?"
What drives such a pronunciation to occur? Is it an #eggcorn? "I haven't come a crossed that before?" (Maybe borrowing from archaic "I'll go a-walking"?)
