rhein

noun. slot, spoor, track, footprint

A noun appearing as N. rhein “slot, spoor, track, footprint” in The Etymologies of the 1930s under the root ᴹ√RUN “flat of hand or sole of foot” (Ety/RUN). It seems to be derived from ᴹ✶runya, with an intermediate form rhoein, where the ancient u became o via a-affection, then this o became œ via i-affection and then later e, while the [[n|y [ı̯] intruded into the preceding syllable]] after the loss of -a made it final.

Neo-Sindarin: This word was adapted as ᴺS. rein in HSD (HSD), with the usual removal of Noldorin-style voiceless rh. However, the actual phonological results in Sindarin would probably be ᴺS. ruin; compare S. ruin “fiery red” with Quenya cognate runya (PM/366). Since ruin already has several meanings in Sindarin, I would retain ᴺS. rein as an obscure dialectical variant.

feminine name. ?Silver-footprint

A name appearing in The Etymologies from the 1930s with a smudged and unreadable character between the b and r (EtyAC/RUN), apparently a combination of celeb “silver” and the lenited form of rhein “footprint”. It might be a variant of Celebrindal “Silverfoot”.
