Correlative Conjunctions
Learn Correlative Conjunctions in English and practice pairing ideas clearly with both...and, either...or, and more.
Correlative conjunctions are pairs of words that work together in one sentence. They connect two equal parts and show a clear relationship between them. Common pairs are both...and, either...or, neither...nor, not only...but also, and whether...or.
Each pair adds a different meaning. Both...and adds two positive ideas. Either...or gives a choice, neither...nor joins two negative ideas, not only...but also adds emphasis, and whether...or presents two possibilities without choosing one.
| Word or Phrase | Definition |
|---|---|
| both...and | It connects two ideas and includes both of them 🤝. |
| either...or | It shows a choice between two options 🔀. |
| neither...nor | It joins two negative options and excludes both 🚫. |
| not only...but also | It adds a second idea with extra focus ⭐. |
| whether...or | It presents alternatives or possibilities without a choice question ❓. |
After correlative conjunctions, the two connected parts should match in form. If the first part is a noun, the second part should also be a noun. If the first part is a phrase or clause, the second part should follow the same pattern. This balance makes the sentence clear and natural.
| Rule |
|---|
| Use the same grammatical form on both sides of the pair ⚖️. |
| Match noun with noun, phrase with phrase, and clause with clause 🧩. |
| Keep the sentence balanced, especially after not only...but also and whether...or 🎯. |
The first word of the pair usually comes directly before the first connected element, and the second word comes before the second connected element. This helps the reader see what is being linked. In questions, the pair still marks two balanced choices or ideas.
| Rule |
|---|
| Place each part of the pair close to the words or clauses it connects 📍. |
| Use the same pattern in statements and questions when the pair links equal elements 🔗. |
| Move the pair carefully if the sentence changes, so the linked parts stay clear 👀. |
When a correlative pair links subjects, verb agreement can depend on the pair and on sentence style. With both...and, the verb is usually plural because two subjects are included. With either...or and neither...nor, many speakers make the verb agree with the nearer subject, especially in formal writing. Usage can vary, so clear balance is more important than memorizing one absolute rule.
| Rule |
|---|
| Use a plural verb after both...and when it joins two subjects 👥. |
| With either...or, the verb often agrees with the subject closer to it 🧲. |
| With neither...nor, the verb often agrees with the subject closer to it 🧲. |
| Choose a structure that sounds balanced and clear if different agreement patterns are possible 🛠️. |
Not only...but also often needs careful structure because the two parts should match closely. The first element can also move for emphasis, especially in formal style, but the balance between the two linked parts should stay the same. Whether...or can link words, phrases, or clauses, and some speakers add not before the second part while others do not. In these cases, parallel structure and clear meaning matter most.
| Rule |
|---|
| Keep the two parts after not only...but also as parallel as possible ⭐. |
| A more formal style may move not only before a verb or clause, but the linked parts should still match 🏛️. |
| Whether...or can connect equal alternatives at different sentence levels, from words to clauses 🌿. |
| Some speakers use whether...or not, while others use whether...or, and both can be acceptable when the meaning is clear 🤔. |
