I (think I) know how to pluralize an indirect quote, e.g.,
Their survey answers were limited to yeses and nos.
But how do I pluralize a direct quote ending in a punctuation mark? Am I even allowed to retain the punctuation mark for emphasis?
In other words, would the correct form(s) be:
- There was no shortage of "How do you do?"s and "Let's do lunch!"es at the networking event.
- There was no shortage of "How do you do"s and "Let's do lunch"es at the networking event.
- There was no shortage of how-do-you-dos and let's-do-lunches at the networking event.
- [something else altogether]
Does the number of correct forms change when I elect to italicize quotes, rather than demarcate them with quotation marks?
A/N: I was trying to keep my example short, but I do realize that "how-do-you-do" is already an established phrase. Hyphenation seems unwieldy, however, if the quote were longer.
