Zoomerang96
ONE love, blood, life
The pronunciations [ahy-ther] and [nahy-ther] with the /aɪ/[ahy] vowel of bite, occur occasionally for these words, chiefly in the speech of the educated and in the network standard English of radio and television. Both the /i/[ee] and /aɪ/[ahy] pronunciations existed in British English, and in the 19th century the /aɪ/[ahy] came to predominate in standard British speech. In American English, therefore, it reflects a recent borrowing from British speech rather than a survival from the time of early settlement, influenced as well by the ei spelling, which is pronounced as /aɪ/[ahy] in such words as height and stein.
