Etymology
Alteration (after either) of nauther, from Middle English neiþer, from Old English nāwþer, contraction of nāhwæþer, corresponding to no + whether. Compare Latin neuter (“neither”). By surface analysis, not + either.

- adjective Not either; not the one or the other.
- conjunction not either; generally used to introduce the first of two or more coördinate clauses of which those that follow begin with nor. Fight neither with small nor great, save only with the king. 1 Kings xxii. 31.
