Couldn't find much on this particular stylistic method, but I was wondering: how would one emphasize only part of a word in an informal novel-like case?
"It wasn't new in any way—just newer."
"It wasn't new in any way—just new-er."
I understand that this is likely to be a stylistic choice, but is simply italicizing the "-er" in "newer" and hoping the reader is able to differentiate it as the emphasis good enough? Or is using a hyphen more or less necessary in this case?
