Can someone explain why I need to set off the adverb like with commas? I saw The New Yorker use it in a recent article,
A senior defense official told me that Kahl was surprised by whom he was about to contact: “He was, like, ‘Why am I calling Elon Musk?’ ”
though I needed to double check to see whether it’s just another case of the magazine’s idiosyncratic typographical style. But then Merriam-Webster also used it in its example, and so did Google (Oxford) Dictionary, who curiously did not do the same for its second example.
I find this first comma really odd. It’s not a prosodic comma, as far as I can tell, because no one pauses after “was” (but does after “like”). I’d also understand if it was an adverbial phrase, but it’s not! I don’t see anyone cutting off other adverbs like this either. (“She was, very, mad.” [?])
So, grammarians, why do I need the first comma?
