et al. with an apostrophe [duplicate]
I want to use the possessive noun form with et al. as in
et al.'s versus et al.
Solution 1:
The grammatically correct way is "Einstein et al.'s paper", because to indicate possession by a noun phrase in English, the 's should be applied to the end of the phrase. However, I don't believe this specific construction is used much, as to me that looks somewhat unusual and feels informal. I'd recommend using a different wording like "the paper of Einstein et al." or "Einstein, Podolsky and Rosen's paper".
