Usage notes

• Neither is used to mean none of two or more. Although some suggest that using the word neither with more than two items is incorrect, it has been commonly used to refer to more than two subjects since the 17th century. The more modern usage does prefer none with more than two things.

• When used in the set phrase me neither, neither is invariably pronounced -iːðə(r).

• There is considerable variation in the number of the verb employed with this construction.
