Endor place-name "Middle-earth" (SA:dôr, NDOR), "centre of the world" (EN); also long form Endórë "Middle-earth" (Appendix E); allative Endorenna "to Middle-earth" in EO. The form Endór in MR:121 may be seen as archaic, intermediate between Endórë and Endor (since long vowels in a final syllable are normally shortened: Endór > Endor). Endór functions as an uninflected genitive in the source: Aran Endór, "King of Middle-earth".
Endamar place-name "Middle-earth" (EN, MBAR, NDOR). However, Middle-earth is normally called Endor, Endórë.
námo (2) noun "a person, somebody" (PM:340 writers may prefer the synonym quén to avoid confusion with # 1)
kemen noun "earth"; see cemen.
mar (1) noun "earth" (world), also "home, dwelling, mansion". Stem mard- (VT46:13, PE17:64), also seen in the ablative Mardello "from earth" (FS); the word is used with a more limited sense in oromardi "high halls" (sg. oromar, PM17:64), referring to the dwellings of Manwë and Varda on Mt. Taniquetil (Nam, RGEO:66). The initial element of Mardorunando (q.v.) may be the genitive mardo (distinguish mardo "dweller"). May be more or less identical to már "home, house, dwelling" (of persons or peoples; in names like Val(i)mar, Vinyamar, Mar-nu-Falmar, Mardil) (SA:bar, VT45:33, VT47:6). Már is however unlikely to have the stem-form mard-; a "Qenya" genitive maren appears in the phrase hon-maren, q.v., suggesting that its stem is mar-. A possible convention could therefore be to use már (mar-) for "home, house" (also when = household, family as in Mardil, q.v.), whereas mar (mard-) is used for for "earth, world". Early "Qenya" has mar (mas-) "dwelling of men, the Earth, -land" (LT1:251); notice that in LotR-style Quenya, a word in -r cannot have a stem-form in -s-.
-wë a suffix occurring in many personal names, generally but not exclusively masculine (Elenwë is the sole certain example of a fem. name with this ending); it is derived from a stem simply meaning "person" (PM:340, WJ:399). In Etym, -wë is simply defined as an element that is frequent in masculine names, and it is there derived from a stem (WEG) having to do with "(manly) vigour".
-o (2), also -ó, "a person, somebody", pronominal suffix (PM:340)
Ambarenya, older [MET] Ambarendya place-name "Middle-earth" (but the more usual word is Endor, Endórë) (MBAR)
earth, soil, land
cemi noun "earth, soil, land"; Cémi ("k")"Mother Earth" (LT1:257; the "Qenya" word cemi would correspond to cemen in LotR-style Quenya)
person, an individual
nassë (1) "a person, an individual" (VT49:30). Also translated "true-being" (pl. nasser is attested), the inner "true" being of a person. With a pronominal suffix in the form nassentar "their true-being" (PE17:175, cf. -nta #2), in the source referring to the "true" spiritual nature of the Valar, as hidden within their visible shapes. The word nassentar would seem to be plural, *"their true-beings". Not to be confused with the verb nassë/násë "he/she is"; see ná #1.
