Definition:
Either is an adjective that is used to describe the inclusion of both possibilities in an argument.
Rules:
It is placed before the noun it modifies and emphasizes that either of the possibilities is valid.
Examples:
1. She brought either dress to the event.
2. If you have either of these keys, you can open the box.
3. I won’t satisfy either possibility unless absolutely necessary.
Tips:
Be aware of the different uses of either when used as an adjective. It is important to recognize the context in which either is used to correctly interpret its meaning.
Definition:
as a pronoun, 'either' is used to refer to one of two choices or possibilities previously mentioned or understood from the context.
Rules:
'Either' can be used to refer to one of two things, people, or situations that have been mentioned.
Examples:
Either of the options works for me.
I don't like either of the candidates.
Either is acceptable.
Tips:
'Either' as a pronoun is often used with 'of' followed by a plural noun or pronoun. Avoid using 'either' when referring to more than two options; it is specifically for two choices.
Definition:
As an adverb, 'either' is used for emphasis in negative sentences to indicate that a negative condition also applies to another subject or object.
Rules:
'Either' can be used at the end of a sentence or clause to emphasize that what is said applies to more than one subject or object.
Examples:
I don't like spinach, and my brother doesn't either.
She's not attending the meeting, and I'm not either.
He didn't pass the test, and she didn't either.
Tips:
When used as an adverb, 'either' usually appears at the end of the clause. Avoid using 'either' as an adverb in affirmative sentences; it's used to emphasize negation.
Definition:
as a conjunction, 'either' is used to introduce the first of two alternatives in a correlative conjunction pair 'either...or.'
Rules:
'Either' can be used to introduce the first of two alternatives, usually followed by 'or' introducing the second alternative.
Examples:
You can either stay or leave.
Either you fix this, or I will.
He will either come on time or not come at all.
Tips:
Make sure to complete the 'either...or' structure; leaving it incomplete can create confusion. Avoid using 'either' with 'nor'; the correct pair is 'neither...nor.'
