ëaron

ocean

ëaron noun "ocean" (PE17:27), also airon. Cf. ëar.

eäron

noun. ocean, great sea

airon Archaic

noun. ocean

An (archaic) word for “ocean”, an augmentative form of airë mentioned in a couple of later notes (PE17/27, 149). A more modern form is ëaron.

Conceptual Development: The form ᴹQ. airen appeared in parenthesis beside ᴹQ. aire “sea” in The Etymologies of the 1930s (Ety/AY). Helge Fauskanger suggested that it might be a genitive form (QQ/airë), but in notes on The Feanorian Alphabet from the 1930s, aire “sea” >> airen (PE22/23 note #70), suggesting it is an alternate (augmentative?) form. If so, it is probably a precursor to airon.

ëaren

noun. ocean, great sea

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.
