A noun in The Etymologies of the 1930s glossed “pool” derived from the root ᴹ√LIN of the same meaning (Ety/LIN¹).
Conceptual Development: A similar word ᴹQ. linde “pool” appears in the Declension of Nouns from the early 1930s (PE21/10), but this word is probably best avoided, as it clashes with Q. lindë “singing, song” (PE17/80).
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.
