來自古英語nahwaether,兩者都不，來自na,不，沒有，詞源同no,hwaether,兩個中的一個，即whether,后受either影響拼寫俗化。

neither

neither: [13] Despite the two words’ similarity, neither is not just either with a negative prefix tacked on. It comes ultimately from Old English nāhw?ther ‘neither’, a compound formed from nā ‘not’ (which survives as no in modern English ‘whether or no’) and hw?ther ‘which of two’ (ancestor of modern English whether). In the late Old English period it was contracted to nawther, and in Middle English, under the influence of either, this became transformed into neither.
=> whether

neither (conj.)

Old English nawter, contraction of nahw?ter, literally "not of two," from na "no" (see no) + hw?ter "which of two" (see whether). Spelling altered c. 1200 by association with either. Paired with nor from c. 1300; earlier with ne. Also used in Old English as a pronoun. As an adjective, mid-14c.
