Plurals

Q. To correctly style the plural of a word as word, or phrase as phrase, (1) do we italicize the core word and leave the s or es ending in roman type: An excessive number of hads, hases, hises, hes, shes, ises, whereases, yeses, nos, etc.? Or (2) should the items be in roman: An excessive number of hads, hases, hises, hes, shes, ises, whereases, yeses, nos, etc.? Or (3) should the items be in roman, enclosed in quotation marks: An excessive number of “hads,” “hases,” “hises,” “hes,” “shes,” “ises,” “whereases,” “yeses,” “nos,” etc.? Please, no recasts.

A. None of these choices are beautiful to look upon. Rewording is the solution (e.g., “too many instances of had, has, his, he, she, is, whereas, yes, no, etc.”), but since that is not an option for you, go with (2) in the spirit of CMOS 17, 7.14.
