gaear
noun. sea
A word for “sea” variously attested as gaear (PE17/027; PM/363; WJ/400), gaer (PE17/27; PE17/149), and aear (Let/386; RGEO/65) in later writings. Of these, I prefer gaear for purposes of Neo-Sindarin, reduced to gaer in compounds.
Possible Etymology: The presence or absence of the initial g- depends on whether the word’s root is √AY(AR) (as it appears in The Etymologies and some later writings) or √GAY(AR) (as it appears in other later writings). See the entry of the root √GAY(AR) for a discussion of this vacillation. Similarly, the form gaer appears primarily as an element in compounds, and can be explained as a reduced form of gaear in that context. For these reasons, this entry uses gaear as the ordinary Sindarin word for “sea”. This has the additional advantage of disambiguating it from the adjective gaer “dreadful”.
Conceptual Development: This word appeared as N. oer or oear “sea” in The Etymologies of the 1930s, reflecting the Noldorin sound change of ai to oe (Ety/AY). However name for the “Great Sea” was N. {Belegar >>} Belegaer in the narratives of this period (LR/19), and the name N. Rhûnaer “Eastern Sea” appeared in draft Lord of the Rings maps from 1943 (TI/307). The element N. oer did appear in the day-of-the-week name N. Aroeren “✱Sea-day” in drafts of The Lord of the Rings appendices, but this was revised to S. Oraeron (PM/130, 138).
tirith aear
place name. Sea-ward Tower
A tower in Dol Amroth mentioned in the preface to the Adventures of Tom Bombadil (TR/192), glossed “Sea-ward Tower”. It is a combination of tirith “watch” and either aear or gaear “sea” (lenited), so perhaps a more literal translation would be “Sea Watch”.

aear (ocean); pl. aeair. The shorter form aer (for N oer) is maybe best avoided since it can be confused with aer "holy", unless the latter is actually a lenited form of gaer. Forms with g-, representing an alternative concept of the word for ”sea”: gaear (i **aear) (ocean), pl. gaeair (i ngaeair = i ñaeair) (PM:363), also gaer (i **aer, no distinct pl. form except with article: i ngaer = i ñaer), but homophones of the latter mean "reddish, copper-coloured, ruddy" and also "dreadful, awful, fearful; holy".

belegaer
place name. Great Sea
Name of the “Great Sea” lying between Middle-earth and Valinor (S/37). This name is a compound of beleg “mighty” and gae(a)r “sea” (SA/beleg, gaer; PM/363).
Conceptual Development: In Silmarillion drafts from the 1930s, this name first appeared as N. Belegar (LR/14), soon revised to Belegaer (LR/19). In The Etymologies, it appeared as Belegoer (Ety/ÁLAT, AY, BEL), a reflection of Tolkien’s uncertainty on whether the diphthong [[n|[ai] became [oe] or [ae]]]. In the later Silmarillion revisions from the 1930s, he used Belegaer consistently following the [[n|revision of [oe] to [ae]]].
