§ Elberil (RS:68)
This is a variant of later Elbereth and it obviously contains el- ’star’ N only in names (EL-). The latter element of Elbereth is bereth from Barathī *’Queen’ with i-affection (BARATH-). Likewise, #beril *’lady, queen’ is probably derived from the shorter stem BAR- yielding words for ’save, rescue’, but: original significance probably ’raise’. The stems BAR-, BARATH- and BARÁD- (the last produces words like ’lofty’, ’sublime’) are all cross-referenced in The Etymologies, being apparently related. Compare also Adunaic bār ’lord’ or ’king’ (SD:428,437).
For the feminine suffix -il compare brannon ’lord’, brennil ’lady’ (BARÁD-).
