I’m hoping there’s some vaguely-authoritative source for this, but I have a feeling it may be doomed to IMHO. What’s the current most accepted practice for spelling “resume” (as in the document laying out your skills and employment)?
Microsoft Word insists on goofy-quotes over both "e"s, most sites I find online put it over neither, and dictionary.com lists all of them, but titles the page with goofy-quotes only over the second “e.” The American Heritage dictionary lists a historical reference with the accent only over the first “e.”
So…that’s all the possibilities. The historical first-e-only we can discount. Word’s dictionary seems to be the only one that accents both. Neither seems lazy, like I don’t know how to produce the accented e. The second-e-only seems correct to me, since it’s only the second e that’s pronounced atypically, but seems to be a minority hit (admittedly, it’s hard to search on a word that’s differently accented, and spelled the same as a much more common word).
