[The Squatter of Amon Rûdh]

His Quenya name is Elwë Singollo, which sounds much more euphonious. Although I never found it particularly boring, I had noticed the similarity of Thingol and thingy before. I think I used the name Ereyu Thingy in one of the REB episodes, but I forget where.

I think that the real danger in examining Sindarin and Quenya names for real-world parallels is that the names as they stand now are the result of years of invention and development. They follow phonological and grammatical rules that Tolkien devised independently of individual names or characters, so that any search for correspondances is in danger of pointing out nothing but coincidences.

These seem to me no more than private amusements, and as such I have no right or power to object to them, though they are, I think, valueless for the elucidation or interpretation of my fiction...
the bulk of the nomenclature is constructed from these pre-existing [invented] languages, and where the resulting names have analysable meanings (as is usual) these are relevant solely to the fiction with which they are integrated. The 'source', if any, provided solely the sound-sequence (or suggestions for its stimulus) and its purport in the source is totally irrelevant except in case of Earendil...

Since we already know about Eärendil, and since Thingol is pure Sindarin with a definite meaning in that language, I'll just throw the Telerin/Greek (the former intentionally, the latter coincidentally) name Teleporno into the mix and see what can be made of it.
