^ᴺ√ELEK root. “different, strange; other”
|√EL||“lo, behold; star”|
?ᴱ√ELE² root. “?wonder”
A hypothetical early root serving as the basis for Gnomish words having to do with “otherness”, such as G. eleg “other”, G. elfel “different, like something else” and possibly also eltha- “to alter, change”, though the last word seems to have been part of a separate etymological paradigm (GL/32). This collection of words also included G. elm “wonder” and elma- “marvel at, admire”. Similar forms appeared in the 1920s: ᴱN. elvennai “wonderful, marvelous” and ᴱN. elven “wonder, wonderment”, the later with a Qenya cognate ᴱQ. elmenda (PE13/143, 161).
Some of this sense of wonderment may have resurfaced in the root √EL in the Quendi and Eldar essay of 1959-60, where Tolkien said of ELE that “according to Elvish legend this was a primitive exclamation, ‘lo! behold!’ made by the Elves when they first saw the stars” (WJ/360). On this basis, I think it worth concocting an extended Neo-Eldarin root ᴺ√ELEM “wonder, marvel” to salvage the “wonder” words from the 1920s. It might also be worthwhile to concoct an extended root ᴺ√ELEK “different, strange; other” to salvage Gnomish “other” words from the 1910s, but that one is more of a stretch and I no longer recommend its use. Neologisms based on later roots serve better for that purpose.
