A root in The Etymologies of the 1930s glossed “helmet” with extended forms √KHÁRAP and √KHÁRAN (EtyAC/KHAR); one of its derivatives ᴹQ. Eldahar seems to be a precursor to Q. Eldacar “Elfhelm”. There are many other words for “helmet” in Tolkien’s later writing, and this root was probably abandoned.

An unglossed root in The Etymologies of the 1930s with derivatives like ᴹQ. solor “surf” (< ᴹ✶solos) and ᴹQ. Solonyeldi “✱Surf Singers” as another name for the Teleri (Ety/SOL). It is a later iteration of ᴱ√SOLO from the Qenya Lexicon of the 1910s with derivatives like ᴱQ. solme “wave” and ᴱQ. solor “surf”, and was in this period the basis for the name ᴱQ. Solosimpe “Shore Piper” (QL/85). Words in the contemporaneous Gnomish Lexicon like G. thloss “breaker” and G. Thlossibrim = ᴱQ. Solosimpi were derived from primitive thol-, indicating the early form of the root was actually ᴱ√ÞOLO (GL/73), which in Gnomish was intermingled with derivatives of ᴱ√FALA “✱wave” (GL/33, 35).
The etymology of the 1930s ᴹQ. solor “surf” < ᴹ✶solos is problematic, in that it shows final -s > -r, a remnant of ideas from Early Qenya. Tolkien’s use of Q. Falmari “Wave-folk” in later writings as the primary alternate name for the Teleri (S/53; PM/386) calls into question the continued validity of ᴹ√SOL. Nevertheless, I think it is useful to retain this root in Neo-Eldarin to salvage some early words like ᴱQ. sóla “tide”.
