oth

noun. war

A noun for “war” derived from primitive ᴹ✶oktā (Ety/OKTĀ). It is a good example of how double spirants became single in Ilkorin, in this case [kt] > [xθ] (or [θθ]) > [θ].

rôth

noun. cave

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