Citation, Documentation of Sources

Q. I am reviewing musicological literature for my next book. I found the following in one source: “Systematic-objective repetition of a peculiar sonic construct on appropriate instruments as well as in proper contexts loops the targeted mind/s in a revolving grove.” My experience and training have me reasonably certain the author meant groove and not grove, and that in citing, I ought to follow grove with [sic] and a note suggesting the likelihood of groove. On the other hand, the author, by slim chance (and in search of a novel metaphor), might really have his minds looping in groves. What does CMOS suggest?

A. You are the best one to judge, so I would advise you to go with your inclination to add [sic] and suggest that groove might have been meant. Or simply write “[groove?]” instead of [sic ].
