I am wondering if you have noticed how much you use “slip” or “ease” when describing motion. People slip in or out of places; they ease things in or out or off.

My editor has pointed out that I do have a tendency to overuse particular words, and I try to avoid doing so. Part of the problem is that there aren’t that many convenient synonyms for either “slip” or “ease.” “Steal away” carries implications not suited for some characters. So do “sneak”, “sidle,” and “slink.” Some repetitions don’t bother readers, such as “says” or “said,” but others, even if only used a few times in an entire book, stick in readers’ minds.
