An early name for S. Galadriel appearing in Lord of the Rings drafts from the 1940s as a combination of galadh “tree” and the lenited form of rhien “lady” (TI/249). There were also (rejected) variants Rhien and Galdri(e)n.
Conceptual Development: Tolkien soon changed her name to Galadriel (TI/246), but it likely that at this early stage, her name still included galadh “tree”, since Tolkien often represented [ð] with “d” instead of “dh” in Lord of the Rings drafts: compare N. Caradras with S. Caradhras. The derivation of Galadriel’s name from S. galad “light” is probably a later innovation.
An adjective appearing as N. rhîn “crowned” in The Etymologies of the 1930s under the root ᴹ√RIG (Ety/RIG). The long î is probably the result of the vocalization of g before nasal n, from primitive adjective ✱rignā.
Neo-Sindarin: Since initial r unvoiced to rh in Noldorin of the 1930s but not in Sindarin of the 1950s and 60s, most Neo-Sindarin writers adapt this word as ᴺS. rîn “crowned”, as suggested in HSD (HSD).
