Is there a way to pluralize a quotation? E.g.,
He was greeted with a chorus of “Hello”s.
Her daring earned “Ooh”s & “Ahh”s from around the room.
With actual dictionary words (“Hello” in the first example), simple plurals might do, without quotes: “He was greeted with a chorus of hellos.”
With ad hoc onomatopoeic words like “ooh” & “ahh”, though, can I pluralize them without confusing the reader? Is italicizing part of the word acceptable: “Her daring earned oohs & ahhs from around the room”?
