Which pronunciation of either is correct?
Using English phonetics, [ EE-ther ] and [ AHY-ther ] are both correct. As a side note, giving “th” a phonetic Z (or S or F or D) sound is a common mispronunciation that can be corrected with practice.
Is either pronounced eether or ither?
Both pronunciations are correct. I tend to use the long i pronunciation, but sometimes I use long e instead.
How do you pronounce either and neither?
Why do people pronounce either as other?
The majority of the differences between British and American pronunciation can be traced to this period. The reason why the pronunciation /’aɪ. ðə/ even exists is because that’s how a German unfamiliar with the “correct” pronunciation would attempt to pronounce it.
