The ideas expressed here are hers own alone.

Kal said

I found this sentence on the web:

"The ideas expressed here are hers own alone."

I would like a second (or even a third) opinion. Should it read

a) "The ideas expressed here are hers alone."  or

b) "The ideas expressed here are her own alone."

I am looking forward to reading your comments.

I like a best, but b seems technically correct as well.

I think her own expresses the idea that she is alone with these ideas so I would say option B is redundant.  If you change it to, “The ideas expressed here are her own," then they would both be good choices.  The original was not good.

I agree , but let's see why.  

Hers alone   is short for  her ideas alone;     the adverb alone is for emphasis (that the ideas are exclusively hers.) It modifies the verb are.

Her own   is short for her own ideas;    own  is similarly for emphasis, but as adjective to noun ideas.

So those are the 2 constructions that make sense.  

(And putting own and alone together won't do, because each needs to fit with either her or hers   as seen above.  If the intention was stronger emphasis,  this  should  do:

The ideas expressed here are hers, and hers alone.

)

Well that doesn't really explain why.  Best I can do.

a) “The ideas expressed here are hers alone.”

or

c) “The ideas expressed here are her own.”
