A noun in Late Notes on Verb Structure (LVS) written in 1969, given as hanw̃a “seat” and derived from primitive ✶khadmā where dm became nm [χanmā] and then nw (PE22/148). Early iterations of this word also meant “chair”, so this word may have that meaning as well.
Conceptual Development: The earliest “seat” words were ᴱQ. sōra {“seat, throne” >>} “seat” and ᴱQ. sonda “seat, chair” in the Qenya Lexicon of the 1910s under the early root ᴱ√SOŘO [SOÐO] (QL/85-86). Tolkien revised the root to ᴱ√SORO (ÐORO) after which the form sonda was deleted. In the contemporaneous Poetic and Mythological Words of Eldarissa Tolkien had only ᴱQ. sonda “seat” (PME/86).
In The Etymologies of the 1930s Tolkien had ᴹQ. handa “chair” under the root ᴹ√KHAD, but Tolkien revised the root to ᴹ√KHAM “sit” and the Quenya form to ᴹQ. hamma “chair” (Ety/KHAM; EtyAC/KHAM). Tolkien then introduced a new root ᴹ√KHAM “call to, summon”, saying that “KHAM sit (replacing KHAD, cancelled)”, so apparently the root for “sit” reverted back to KHAD. This is supported by the 1969 “seat” word hanwa seen above.
