1. Definition of ‘Either/Or’
The phrase “either/or” is a correlative conjunction used to present two alternatives or choices. It indicates that one, but not both, of the options is possible or true. “Either” introduces the first option, and “or” introduces the second. This construction links words, phrases, or clauses of equal grammatical rank, creating a sense of choice or possibility.
The primary function of “either/or” is to offer a selection between two possibilities. It clarifies that only one of the presented options is valid or applicable in a given context. The phrase is commonly used in both formal and informal settings, making it an essential part of everyday communication. Understanding its proper usage can significantly improve the clarity and precision of your speech and writing.
In essence, “either/or” acts as a grammatical tool to present a binary choice, highlighting the exclusivity of the options. It signals to the listener or reader that a decision needs to be made between the two alternatives provided. This construction is versatile and can be applied in various contexts, from simple everyday choices to complex decision-making scenarios.
2. Structural Breakdown of ‘Either/Or’ Sentences
The basic structure of a sentence using “either/or” is as follows: Either + option 1 + or + option 2. The “either” precedes the first alternative, and the “or” precedes the second. The options presented can be nouns, verbs, adjectives, adverbs, phrases, or even entire clauses, provided they are grammatically parallel. This parallelism is crucial for maintaining clarity and grammatical correctness.
Parallelism means that the elements joined by “either/or” should have the same grammatical form. For instance, if the first option is a noun phrase, the second option should also be a noun phrase. Similarly, if the first option is a verb in the infinitive form, the second option should also be an infinitive verb. Maintaining this consistency enhances readability and avoids grammatical errors.
Here’s a breakdown of the structure with examples:
- Either + Noun + or + Noun: Either coffee or tea.
- Either + Verb + or + Verb: Either study or relax.
- Either + Adjective + or + Adjective: Either happy or sad.
- Either + Adverb + or + Adverb: Either quickly or slowly.
- Either + Phrase + or + Phrase: Either in the park or at home.
- Either + Clause + or + Clause: Either she will come or he will.
The placement of “either/or” is also important. It should be placed immediately before the elements it connects to avoid ambiguity. Misplacing “either/or” can change the meaning of the sentence or make it grammatically incorrect. Careful attention to the structural elements ensures that your sentences are clear, concise, and grammatically sound.
3. Types and Categories of ‘Either/Or’ Constructions
The “either/or” construction can be categorized based on its function and the types of elements it connects. Understanding these categories will help you use “either/or” more effectively in various contexts.
3.1. ‘Either/Or’ as Correlative Conjunctions
As mentioned earlier, “either/or” is a correlative conjunction. Correlative conjunctions are pairs of words that connect related words, phrases, or clauses. Other examples of correlative conjunctions include “both/and,” “neither/nor,” and “not only/but also.” These conjunctions work together to create a balanced and parallel structure within a sentence.
The key characteristic of correlative conjunctions is that they always come in pairs and must be used together. “Either” cannot be used without “or” in this construction, and vice versa. This pairing ensures that the sentence clearly presents two related options or alternatives.
3.2. Expressing Alternatives
One of the primary uses of “either/or” is to express alternatives. It presents two different options, indicating that only one of them can be chosen or is true. This is common in situations where there is a need to select between two possibilities.
For example:
- You can either take the bus or walk to school.
- We can either eat at home or go to a restaurant.
- She will either study medicine or pursue engineering.
In each of these sentences, “either/or” presents two distinct alternatives, implying that only one of them will be chosen or is possible.
3.3. Presenting Choices
“Either/or” is also used to present choices, often in the form of questions or suggestions. It allows the speaker or writer to offer two options for consideration, leaving the decision to the listener or reader.
For example:
- Would you like either coffee or tea?
- Should we go to either the beach or the mountains?
- Do you want to watch either a movie or a TV show?
These sentences present choices, inviting the other person to select between the two options provided. The use of “either/or” makes it clear that only one of the options should be chosen.

5. Usage Rules for ‘Either/Or’
To use “either/or” correctly, it’s essential to follow certain grammatical rules. These rules ensure that your sentences are clear, concise, and grammatically sound.
5.1. Subject-Verb Agreement
When using “either/or” with singular and plural subjects, the verb agrees with the subject closest to it. This rule is crucial for maintaining grammatical accuracy.
For example:
- Either the student or the teacher is responsible. (Singular subject “teacher” is closer to the verb)
- Either the teacher or the students are responsible. (Plural subject “students” is closer to the verb)
In the first sentence, the verb “is” agrees with the singular noun “teacher.” In the second sentence, the verb “are” agrees with the plural noun “students.”
5.2. Parallelism
As mentioned earlier, parallelism is a key rule when using “either/or.” The elements connected by “either/or” should have the same grammatical structure. This ensures clarity and avoids confusion.
For example:
- Correct: You can either read a book or watch a movie. (Both options are verb phrases)
- Incorrect: You can either read a book or watching a movie. (One option is a verb phrase, and the other is a gerund phrase)
The correct sentence maintains parallelism by using two verb phrases. The incorrect sentence violates parallelism by mixing a verb phrase with a gerund phrase.
5.3. Avoiding Double Negation
When using “either/or,” avoid double negation. Double negation occurs when you use two negative words in the same clause, which can create confusion and change the intended meaning.
For example:
- Incorrect: I don’t want either coffee or tea.
- Correct: I want neither coffee nor tea. (Use “neither/nor” instead)
- Correct: I don’t want either coffee, or do I want tea.
The incorrect sentence uses “don’t” and “either,” creating a double negative. The correct sentences avoid double negation by using “neither/nor” or restructuring the sentence.
5.4. Placement of ‘Either/Or’
The correct placement of “either/or” is crucial for clarity. It should be placed immediately before the elements it connects to avoid ambiguity.
For example:
- Correct: You can either stay here or go home.
- Incorrect: You can either stay or go here home.
The correct sentence places “either” before “stay” and “or” before “go,” clearly connecting the two options. The incorrect sentence misplaces “either” and “or,” making the sentence confusing.
6. Common Mistakes with ‘Either/Or’
Even with a good understanding of the rules, it’s easy to make mistakes when using “either/or.” Here are some common errors and how to avoid them.
1. Incorrect Subject-Verb Agreement:
- Incorrect: Either the cat or the dogs is going to the park.
- Correct: Either the cat or the dogs are going to the park.
2. Lack of Parallelism:
- Incorrect: You can either eat dinner or a snack.
- Correct: You can either eat dinner or have a snack.
3. Double Negation:
- Incorrect: I don’t want either to go or stay.
- Correct: I want neither to go nor to stay.
4. Misplaced ‘Either/Or’:
- Incorrect: She either will go to the store or the market.
- Correct: She will go to either the store or the market.
5. Using ‘Or’ Without ‘Either’:
- Incorrect: Or you can stay home.
- Correct: Either you can go out, or you can stay home.
By being aware of these common mistakes, you can avoid them and use “either/or” correctly in your writing and speaking.

You can either study math or science, and either read a book or do practice problems.
2. Implied ‘Either’:
Sometimes, the “either” part of the construction is implied rather than explicitly stated. This is common in informal speech and writing.
For example:
Do you want coffee or tea? (Implied: “Do you want either coffee or tea?”)
3. ‘Either/Or’ with Emphasis:
“Either/or” can be used to emphasize the exclusivity of the choices, highlighting that only one option is possible or desirable.
For example:
It’s either now or never.
4. Complex Clause Structures:
“Either/or” can connect complex clauses with multiple elements, requiring careful attention to parallelism and grammatical accuracy.
For example:
Either she will complete her degree and find a good job, or she will travel the world and gain new experiences.
9. Frequently Asked Questions (FAQ)
