A word given only in its plural form {únexi >>} únehtar as term for “the smallest quantities possible” (NM/250 note #1; NM/265 note #6). It appeared in a discussion distinguishing the platonic ideal of IRON and GOLD from the tiny components making up such matter. As suggested by Carl Hostetter, it seems to be based on a negated form of the root √NEK “divide”, so more literally “*indivisible [thing]”. As such, it is probably the Elvish word for “*atom”, whose original meaning in ancient Greek was similar.
