I'm having trouble reconciling two passages:
From The Departure of Boromir in the two towers:
’S is for Sauron,’ said Gimli. ’That is easy to read.’ ’Nay!’ said Legolas. ’Sauron does not use the Elf-runes.’ ’Neither does he use his right name, nor permit it to be spelt or spoken,’ said Aragorn.
In, I think, The Shadows of the Past, it is clear that the inscription on the Ring is in Elf script. The page on the Ring on this site says it is in Tengwar alphabet.
Does Tengwar script not count as 'Elf-runes', or is there a gap in Legolas' Ring-lore?
