Q: We are having a discussion about –ic and –ical. Dictionaries often use both. Where does the AMA Manual stand on this?
A: Please refer to the Correct and Preferred Usage chapter in the manual. You’ll see an entry on this very subject. In addition, there are entries on some of the pairs of words where the meaning of the –ic version is different from that of the –ical version (eg, classic/classical, historic/historical).
Q: Does AMA style advise against using a period after the abbreviation Inc?
A: Yes, we advise against using a period after the abbreviation Inc. This is addressed in section 14.7.
Q: In the course of developing a manuscript, an author has retired. Should we delete her affiliation? Or perhaps indicate something about her retirement in parentheses?
A: I would list the author’s affiliation, assuming she was affiliated with this institution while working on the paper. Then, follow the guidance about Author’s Affiliation (section 2.3.3) if a person has moved. This would mean adding an indication that Dr X is now retired. The style used for this notation will depend on the design of the journal involved. —Cheryl Iverson, MA
