An archaic word for “sea” which fell out of use to due conflict with “holy” words like aira or airë; it was a noun form of primitive ✶gaı̯ră (PE17/27). The more common modern word for “sea” is ëar.
Conceptual Development: ᴹQ. aire “sea” appeared in The Etymologies of the 1930s as a derivative of ᴹ√AYAR (Ety/AY); it appeared beside a form ᴹQ. airen that might be a genitive form, or might be a longer form; see the entry on ᴹQ. airon for discussion.
[airë (3) noun "eternity" (EY, VT45:13)]
