Either

(ē’ther, or ī’ther. The former is the pronunciation given in nearly all the English dictionaries, and is still the prevailing one in the United States; the latter has of late become somewhat common in England. Analogy, however, as well as the best and most general usage, is decidedly in favor of (ē’ther), a. or pron. [A-S. āghther, āghvādher, āhrādher, ārther, audher, from ā, ō, ever, and hwæðer, whether; O. H. Ger. ioedgar, M. H. Ger. iepedēr, N. H. Ger. jeder, D. ieder. See EACH and WHETHER.]
