Frodo's Elvish qualities - nature or nurture?

[Cazoz]

I was thinking about something whilst re-reading the Fellowship the other day.

Frodo obviously has an Elvish likeness about him and I was wondering whether you guys thought this was nature or nurture related?

With nature I refer to a marked difference in his appearance which is mentioned several times, particularly in regards to his eyes. There may also be an element of destiny involved, that is has perhaps been ordained for him to undergo many 'unHobbit-like' tasks in his life and that it was his fate. Thus he was maybe born with a more ethereal, Elvish sense. This may, furthermore, explain his prophetic and telling dreams.

With nurture I refer to his environs. Familiar with Gandalf, through Bilbo, he has been exposed to many things Elvish. He speaks it to a proficient degree for one, and has been emmersed in lore and tales of adventures involving Elves through living at Bag End with Bilbo. He is at once more comfortable than the others with Gildor, for one, recognising the status of these Elves and their intentions through the realisation of Elbereth in their song. One curiosity is his own use of Her name whilst being attacked at Weathertop. Where does this come from?

What do you guys think is responsible for him being so much more Elvish than the other Hobbits, even Bilbo who has been interacting with Elves for far longer?

Could some of these principles be applied to Faramir, who I believe and I think many would agree, had definitely more of an Elvish quality than other Men of his kin. Is this anomalous Numenorean blood of old, which has somehow brought out Elvish qualities in him, and yet warrior-like ones in his brother?
