Hope and Hopelessness

[Firnantoonion]

Are you referring here to the Old Hope that is mentioned in the Athabeth?

yes, I were. and i agree with you that Aragorn means Admir, for one without Estel, would've not continued on the quest.
(poor Boromir, it seems to me that the ring took away his estel, as Sauron did by Denethor)

And the colour green is also the colour of hope in the Netherlands, so I guess that it is this in the rest of Europe too. (at least in England, I think)
