A word appearing as Eären “Great Sea” (PM/363) and eäron “ocean” (PE17/27), possibly also an element in the name Eärenya “Sea-day” (LotR/1110).
Conceptual Development: A form ᴹQ. earen appeared in The Etymologies of the 1930s as a parenthetical form beside ᴹQ. ear “sea”; this might be a genitive form, but I suspect it is an early appearance of earon/earen “ocean” instead.
ëaren noun "eagle" or "eyrie" (LT1:251; this early "Qenya" word is evidently no more valid than ëa "eagle" in LotR-style Quenya.)
