1. Definition and Role of “Either” in English Grammar
The word “either” functions primarily as a determiner, pronoun, or conjunction in English. Its core purpose is to present a choice or alternative between two or more options. It indicates that at least one of the options will be true, applicable, or acceptable, but not necessarily both simultaneously.
Classification and Function
- As a determiner: “Either” modifies a noun to specify one of two options. For example: Either book is fine.
- As a pronoun: “Either” replaces a noun to refer to one of two possibilities. For example: Either of these is acceptable.
- As a conjunction: “Either” is used with “or” to connect two options, forming “either…or” structures. For example: You can have either tea or coffee.
Contexts of Use
Sentences with “either” are commonly used in contexts where choices, alternatives, or conditions are being discussed. These include formal and informal communication, written and spoken language, and in various grammatical structures like conditional sentences, questions, and negative sentences.
2. Structural Breakdown of Sentences with “Either”
Basic Pattern: “Either…or”
The most common structure involves pairing “either” with “or” to connect two options:
| Pattern | Example |
|---|---|
| Either + Option 1 + or + Option 2 | Either you come with us or stay at home. |
In this structure, “either” introduces the first option, and “or” connects it to the second. The options can be nouns, pronouns, phrases, or clauses.
Sentence Components
- Option 1: The first choice, which can be a noun, pronoun, or clause.
- Option 2: The second choice, also a noun, pronoun, or clause.
- “Either”: The word indicating the choice or alternative.
- “Or”: The coordinating conjunction linking the options.
Placement and Agreement
When “either” is used as a determiner or pronoun, it must agree in number and form with the noun it modifies. When used with “or,” the verb agreement depends on the nearer subject or noun.
3. Types and Categories of “Either” Sentences

These sentences directly present two options, often with a straightforward structure:
- Example: Either you finish your homework or you can’t watch TV.
