Let's say I've put forward an idea to a number of people and each person has several different objections to it.
I know I can say:
What are each individual's objections?
– OR –
What are the objections for each of them?
But can I say:
What are each of them's objections?
It sounds awkward, but is it wrong? I don't want to say:
What are each of their objections?
Because the "their" in that sentence refers to all the people and therefore all the objections. What I want is to ask for the objections grouped by person.
Also can I say:
What are each's objections?
Best Answer
The best way to structure this statement will not only depend on the goal of the statement itself, but also on the body of text which surrounds it. In all cases, you must indicate who "they" or "them" are, either in this statement or another. Since here, I assume you are referring to a group of individuals, such must be identified in close proximity.
To directly answer your question, "them's" and 'each's" are not possessive forms, so no.
One suggestion might be:
What are the objections of each individual?
or
What are the objections of each? (Depending on how the individual was defined in the preceding text)
