I found it interesting that the finding of the Ring by Bilbo seemed to be inspired by the Rankin-Bass The Hobbit TV movie . In the book, Bilbo finds the Ring in the dark and there is more of a sense of fate working, In now both the Rankin-Bass and Jackson Hobbit films Bilbo finds the ring by the gleam of the sword Sting. Also interesting that in both movies - the time riddle is echoed by a unseen voice - in Rankin Bass this is not known in Jackson it is Gollum but not seen.
* noted Tolkien academic and linguist Carl Hostetter has very helpfully advised me that 'the title "Ósanwe-kenta" means "Enquiry [into] (_kenta_) [the] Communication of Thought (_ósanwe_)". So "communication of thought, telepathy" is just _ósanwe_. so the actual act that may be going on btw Galadriel and Gandalf would be called ósanwe- thank you Carl for catching this)
Given his rather prominent (and recurring) role in the movie I also thought about the etymology of the name AZOG in The Hobbit. According to John Rateliff's History of The Hobbit the name might have its origin in Tolkien's Mago/Magol constructed language which is said to have been inspired by Hungarian (and is yet to be published) (Rateliff, 2007, p.787).
Will want to get a transcript of this and analyze. The Elvish all seemed to make sense from what was being said. I was trying to figure what was on Elrond's desk in Rivendell,
