OK, but please don't do what pg did a year or so ago and dismiss anyone who wrote "delve" as AI writing. I've been using "delve" in speech for 15+ years. It's just a question where and how one learns their English.
Word converts any - into an em dash based on context. Guess who’s always accused of being a bot?
The thing is, AI learned to use these things because it is good typographical style represented in its training set.
