Earlier name of S. Sarn Gebir in Lord of the Rings drafts from the 1940s (TI/366). Its initial element is sarn “stone”, but the meaning of its second element is unclear. Some possibilities were suggested by Roman Rausch (EE/2.39, 2.40).
sarnas
noun. cairn
A noun for “cairn” (a memorial made of a pile of stones) inx the name N. Sarnas Fingolfin “Cairn of Fingolfin” from a list of names associated with Silmarillion drafts of the 1930s (LR/406). It is an elaboration of N. sarn “stone”.
Conceptual Development: An earlier word G. dal “cairn” appeared in the Gnomish Lexicon of the 1910s near the words G. dalech “(upright) stone” and G. daltha- “to erect, set up” (GL/29), so perhaps based on ᴱ√TALA (or ✱DALA) “support” (QL/88).
