either, neither

The quantifiers either and neither are a kind of determiner. We use them to talk about possible choices between two people or things.

When used as a determiner, either and neither must come before a singular countable noun.


Either is positive (+). It means "one OR the other" (of two).


Neither is negative (-). It means "not one AND not the other" (of two).

We can pronounce each of the words either and neither in two different ways:
either: /'i:ðə/ OR /'ʌɪðə/
neither: /'ni:ðə/ OR /'nʌɪðə/

Either pronunciation is acceptabe. Neither pronunciation is wrong.
