Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
ekko
noun. spine, thorn, point
ekkoita-
verb. to awake
A verb for “awake” appearing in its past or perfect form ekkoitanie “might awake” in Koivienéni sentence from the late 1930s (VT27/7), probably a combination of ᴹQ. et “out” and the verb ᴹQ. koita-.
Neo-Quenya: For purposes of Neo-Quenya, I prefer to use the verb ᴺQ. cuita- for “to waken, rouse”.
(ek)koiru-
verb. to come to life
A verb appearing as {ekkoitu >>} (ek)koiru “come to life” in the Quenya Verbal System (QVS) from 1948 (PE22/112), a u-verb based on the root ᴹ√KOY “live” with the (optional) prefix ᴹQ. et-, where tk became kk as it did in cases where it did not undergo metathesis to kt > ht.
A noun for “spine” in The Etymologies of the 1930s under the root ᴹ√EK (Ety/EK; EtyAC/EK). In The Etymologies as published in The Lost Road it was given the gloss “spear” (LR/355), but Carl Hostetter and Patrick Wynne corrected this to “spine” in their Addenda and Corrigenda to the Etymologies (VT45/12). In notes on The Feanorian Alphabet from this same time period, ekko was glossed “point, spine, thorn” (PE22/23).
Conceptual Development: The Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s had ᴱQ. ekke (ekki-) “thorn” derived from the early root ᴱ√EKE (QL/35; PME/35). Early Noldorin Word-lists of the 1920s had ᴱQ. ehta as a cognate to ᴱN. aith “thorn” in a draft entry (PE13/136), likely based on ✱ekta.
