Ilk. rôth (rodh-) n. “cave” (Category: Cave)
A Doriathrin noun for “cave”, also appearing as roth, derived from primitive ᴹ✶rǭda or ᴹ✶roda (Ety/ROD, EtyAC/ROD). The [d] spirantilized to [ð] (“dh”) as usual, then after the final vowel was lost the final [ð] became [θ] as suggested by Helge Fauskanger (AL-Doriathrin/roth). The original sound [ð] is preserved in the plural rodhin.
