• Word use-pairs. That is, a slightly unusual or otherwise attention-catching word used twice in succession. Separated by several sentences in a paragraph, usually.
• Overused basic building-block words: moment, realize, suddenly.
• Weasel adverbs not in dialog (and sometimes even there): very, rather, quite, and their milquetoast friends.
• Unusual words used more than one in the entire story, even widely separated. (For instance, in "Initiation" I stomped out one use of "forestall", because I thought the story could handle at most one instance of it.)
• A repeated dialog pattern: "Short phrase," he said. "Longer stretches of dialog follow that initial break."
There are other things that I don't consider errors on my part that I try to smooth over as I go. I mentioned a few of them in my earlier post about line editing.
Not that my Rupertus Domesticus story is in this stage yet. Sigh. Still struggling.
