A word appearing as ᴱQ. ondole “a stone monument” in the Qenya Lexicon of the 1910s as an elaboration of ᴱQ. ondo “stone” (QL/70). In the Poetic and Mythological Words of Eldarissa it was glossed “stone-cairn” (PME/70).

Neo-Quenya: Since ondo “stone” survived in Tolkien’s later writings, I would retain ᴺQ. ondolë for a monument or cairn made of stone (either refined or rough).
