[William Cloud Hicklin]

but in the language section describes the Silvan tongues as not-Eldarin [although not Eldarin doesn't necessarily mean Avarin]

In 'Quendi and Eldar' (1959-60) Nandorin (and thus its derivatives Ossiriandic and Silvan) is expressly stated to be of Lindarin/Telerin origin, and therefore Eldarin.

This had been a question mark ca. 1936, it seems, since in the 'Lhammas' (B-version) the tongue of the 'Danians' was "like that of Doriath, but not the same" (amended from the A-text in which it was wholly unlike the speech of the Eldar and Beleriandic Ilkorins). But then in 'Lammasethen' Danian appears as a 'middle Quendian', neither Eldarin nor 'Lemberin'/Avarin (however, Thingol's folk are there promoted to 'Eldar').



The footnote to Appendix F is interesting. It doesn't appear in the first draft of that Appendix, written before the Great Linguistic Upheaval ca. 1951-52. From that time we find in the Grey Annals, entry VY 1350, that the Nandor (there so named for the first time) were explicitly Teleri, and so their language was Eldarin.

The App F draft itself alters the Lammasethen conception and distinguishes between Eldarin, Lemberin and Avarin tongues, the Lembi or 'lingerers' at that time incorporating both the Sindar and the Danians/Nandor; the "many secret tongues" of the Avari are said not to come into the LR. At this time of course Lemberin of Doriath and the Vales of Anduin was of course not Sindarin, which didn't yet exist (or more accurately, the language existed but was still called Noldorin and came from Valinor).

But App F as published appears on the face of it to return to the old conception, West-elves of Valinor and Avarin East-elves! (except for the 'promotion' of the Sindar). Indeed, text F4 of the appendix, written after the GLU with Sindarin now ensconced as the native tongue of Beleriand, says in so many words that the native peoples of Lorien and Mirkwood, despite their Sindarin nobility, were Avari: "many were Eastern Elves that had hearkened to no summons to the Sea, but being content with Middle-earth remained there, and remained long after, fading in fastnesses of the woods and hills....Of that kind were the Elves of Greenwood the Great; yet among them also were many lords of Sindarin race. Such were Thranduil and Legolas his son. In his realm and in Lorien both the Sindarin and the woodland tongues were heard; but of the latter notrhing appears in this book."
