Nómesseron pl. noun in genitive: a compound "of place-names", apparently an inflected compound consisting of #nómë "place" + a genitive plural #esseron "of names" (VT42:17; we might have expected *ession, since essi rather than ?esser as the nominative plural of essë "name" is attested both in PM:339 and MR:470)
A word for “place” appearing as an element in names like Ondonórë Nómesseron Minasurië “Enquiry into the Place-names of Gondor” (VT42/17) and Quentalë Ardanómion “✱History of the Places of Arda” (WJ/206). It is also an element in correlative combinations like sinomë “here, in this place” (LotR/967; PE17/67, 103), where it has a short o as the second element in a compound; compare lúmë “time” vs. silumë “now, at this time”.
Conceptual Development: ᴹQ. nome (or ✱nóme) first appeared in correlative combinations in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 as a derivative of ᴹ√NOM “spot, place” (PE23/112), this root replacing ᴹ√MEN of the same meaning (PE23/112 note #141). The rejected root refers back to ᴹQ. men “place, spot” from The Etymologies of the 1930s (Ety/MEN), which in turn had replaced ᴹQ. esse “place” under the root ᴹ√ES when that root was revised to have derivatives like esse “name” instead (EtyAC/ES). The Qenya Lexicon of the 1910s had ᴱQ. lar “region, place” under the early root ᴱ√LAŘA [LAÐA] (QL/51).
