exa

other

exa adj.? "other" (apparently as adjective) (VT47:10, VT49:33). Also eces ("k"), unless this is intended as the stem underlying exa (the root KES with prefixed stem-vowel) rather than a Quenya word (VT49:33).

hyana

adjective. other, other, *another [a different one]

An adjective for “other” in notes from 1968 or later, derived from primitive ✶khyana (VT49/14).

Neo-Quenya: For purposes of Neo-Quenya I would use hyana for “other” and also “an other” or “another” in the sense “a different one”, as opposed to “another” = “one more” for which I would use enta (see below). For example: cennen hyana elda “I saw another elf [different from the one previously discussed]” vs. á anta enta “give me another [one more]”. Saying á anta hyana would mean “give me another [a different one]”.

Conceptual Development: A different note from the late 1960s had exa “other” based on the root √KES (VT47/40). This same note had enta “another: in sense one more (not except by implication ‘another different one’)”, so presumable exa “other” had the sense “another different one”. Notes on Demonstrative, Relative, and Correlative Stems (DRC) from 1948 had ᴹQ. aia(na) “other, different”, also meaning “alien, strange, any other” (PE23/105). It had quite a few rejected variants; see the discussion in the entry on the related pronoun ᴹQ. ai(a)na for discussion.

The Early Qenya Grammar of the 1920s had ᴱQ. nyanya “other (general)” with the additional gloss “alter”, which is Latin for “another, other (of many)” according to Carl Hostetter and Bill Welden (PE14/55 and PE14/56 note #97). The Qenya Lexicon of the 1910s ᴱQ. vāra “other” under the early root ᴱ√VARA (QL/100).
