N. rhîn adj. “crowned” (Category: Hat, Cap)
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 Hiswelókë’s Sindarin Dictionary (HSD).
