Truly? Ah, that is interesting! Well, we have two main dialects, but everyone uses the same script - so if I wished to say "Thank you", I would say "Le hannon" in Sindarin, and "Hantanyel" in Quenya - same letters, different words.

The Men have their own variant, but most use a version of Tengwar as well, and the Dwarves all use Cirth for public writing, and if they have their own private script they do not show it to outsiders.
