You mean "Each person can have his or her own preference".
Singular subject (person), singular object (preference) and singular preposition (his or her).
Oh boy, I stepped in that one. Let's see if I can recover - my use of 'their' was correct, it was my use of "Each person" that was incorrect. Yeah, that's the ticket! So how about 'People can have their own preference'? Does that work? Or does it now need to be 'preferences'? I hate grammar!
Like I said in that thread, some of this is easy for me, but there are many areas I struggle with (like ending sentences with prepositions).
