    [O.N. ei, ey. Cogn. with O.E. ; Mid.Eng. o and oo; Ger. je; LAT. aevum; Gr. agregrigr. The spelling of this and the preceding word in Sc. is irregular, but ay = yes, and aye = always, seem to predominate. Both words in Sc. are markedly diphthongal but not identical in pronunciation. N.E.D. and Un. Eng. Dict. prefer ay = always, and aye = yes, the first of which rhymes with the ay series of Eng. words like say, day, etc., while the second does not. The Concise Eng. Dict. spells ay = yes, and aye = ever, always.]
