”All of your "grrr" examples are correct, flowery.”
As far as I’m aware, they are Americanisms. I’m in the UK, where using them makes someone sound idiotic and as though they watch too much telly. They may technically be “correct”, but I don’t think most people who use them are doing so because they believe the more usual phrases are incorrect grammatically.
”Would you like a link to preposition use, multi-word verbs and the uses of "get"?”
What makes you think I would? How odd. Or passive aggressive.
