Definition of ‘Not Only…But Also’
The correlative conjunction “not only…but also” is used to add emphasis to two related pieces of information. It highlights that both elements are important or noteworthy. The structure connects two words, phrases, or clauses, indicating that the second element is equally or even more significant than the first. This conjunction adds sophistication to writing and speech, making it a valuable tool for clear and impactful communication.
Function: The primary function of “not only…but also” is to emphasize two connected ideas. It signals to the reader or listener that both elements being joined are significant and should be given attention. This contrasts with simply using “and,” which does not necessarily imply the same level of emphasis.
Classification: Grammatically, “not only…but also” is classified as a correlative conjunction. Correlative conjunctions are pairs of words that work together to connect elements in a sentence. Other examples of correlative conjunctions include “either…or,” “neither…nor,” and “both…and.”
Contexts: This conjunction is appropriate in both formal and informal contexts, although its use tends to be more prevalent in formal writing and speech. It’s commonly found in academic papers, business reports, and presentations, as well as in everyday conversations where emphasis is desired.
Structural Breakdown
The structure of “not only…but also” is relatively straightforward, but understanding its components is crucial for correct usage. The basic pattern involves placing “not only” before the first element you want to emphasize and “but also” before the second element. The elements connected must be grammatically parallel.
Basic Structure: Not only + [element 1] + but also + [element 2]
Elements: The “elements” can be nouns, verbs, adjectives, adverbs, phrases, or clauses. The key is that the grammatical structure of element 1 and element 2 must be the same (parallelism). For example, if element 1 is a noun phrase, element 2 should also be a noun phrase.
Example: Not only did she study hard, but also she practiced consistently.
In this example, “did she study hard” and “she practiced consistently” are both clauses.
Grammatical Agreement
When using “not only…but also,” ensuring grammatical agreement is essential for clarity and correctness. This primarily concerns subject-verb agreement and pronoun agreement.
Subject-Verb Agreement: If the elements connected by “not only…but also” act as the subject of a verb, the verb agrees with the subject that is closer to it. This is particularly important when one subject is singular and the other is plural.
Example: Not only the students but also the teacher is going on the field trip.
Not only the teacher but also the students are going on the field trip.
In the first sentence, the verb “is” agrees with “teacher,” which is closer to the verb. In the second sentence, the verb “are” agrees with “students.”
Pronoun Agreement: Pronouns must agree in number and gender with the nouns they refer to, even when those nouns are connected by “not only…but also.”
Example: Not only John but also Mary brought her book.
Here, “her” agrees with “Mary,” the closest noun.
Placement of ‘Not Only’
The placement of “not only” can significantly impact the emphasis and flow of a sentence. Generally, “not only” should be placed as close as possible to the element it modifies.
Beginning of the Sentence: When “not only” begins the sentence, it often requires inversion (the verb comes before the subject). This is a more formal construction.
Example: Not only is she intelligent, but also she is kind. (Inversion: Is she intelligent)
Before the Verb: Placing “not only” before the verb emphasizes the action.
Example: She not only sings beautifully, but also plays the piano.
Before the Subject: Placing “not only” before the subject emphasizes the person or thing performing the action.
Example: Not only the teacher but also the students enjoyed the field trip.
Types of Elements Connected
“Not only…but also” can connect various grammatical elements, each requiring careful attention to parallelism and agreement. Here’s a breakdown of the different types of elements you can connect with this conjunction:
Connecting Nouns
When connecting nouns, ensure both nouns are of the same type (e.g., both concrete nouns or both abstract nouns). The articles (a, an, the) should be used or omitted consistently for both nouns.
Example: He is interested not only in history but also in literature.
Connecting Verbs
When connecting verbs, maintain the same verb form (e.g., both infinitives, both gerunds, or both past participles). This ensures parallel structure and grammatical correctness.
Example: She likes not only to sing but also to dance.
Connecting Adjectives
When connecting adjectives, ensure they are of the same type (e.g., both descriptive adjectives or both limiting adjectives). Place them directly before the nouns they modify.
Example: The movie was not only exciting but also thought-provoking.
Connecting Adverbs
When connecting adverbs, ensure they are of the same type (e.g., both adverbs of manner or both adverbs of time). Place them appropriately in the sentence to modify the correct elements.
Example: He performed not only skillfully but also confidently.
Connecting Phrases
When connecting phrases, ensure they are of the same type (e.g., both prepositional phrases or both infinitive phrases). This maintains parallel structure and ensures clarity.
Example: She is good not only at playing the piano but also at singing.
Connecting Clauses
When connecting clauses, ensure they are of the same type (e.g., both independent clauses or both dependent clauses). Use appropriate conjunctions and punctuation to join the clauses correctly.
Example: Not only did it rain all day, but also the wind was strong.

Advanced Topics
For advanced learners, there are nuanced aspects of “not only…but also” usage that can further refine your understanding and application of this conjunction.
Inversion with ‘Not Only’
When “not only” begins a sentence, it often triggers inversion, where the auxiliary verb comes before the subject. This stylistic choice adds emphasis and formality to the sentence.
Example: Not only did he forget her birthday, but also he forgot their anniversary.
In this case, “did” (auxiliary verb) comes before “he” (subject). Without inversion, the sentence would be: “He not only forgot her birthday, but also he forgot their anniversary,” which is less emphatic.
When to Use Inversion:
- At the beginning of a sentence for emphasis.
- In formal writing or speech.
How to Form Inversion:
- Start the sentence with “Not only.”
- Follow with the auxiliary verb (e.g., is, are, was, were, do, does, did, has, have, had).
- Then, add the subject and the main verb.
- Continue with “but also” and the second part of the sentence.
Formal vs. Informal Usage
While “not only…but also” is appropriate in both formal and informal contexts, there are subtle differences in how it is used.
Formal Usage:
- Complete structure: Always include “also” after “but.”
- Inversion: More common at the beginning of sentences for emphasis.
- Careful attention to parallel structure: Grammatical precision is essential.
Example: Not only is the research comprehensive, but also it is meticulously documented.
Informal Usage:
- Omission of “also”: Acceptable in casual conversation and less formal writing.
- Less strict adherence to inversion: Sentence structure can be more relaxed.
- Emphasis on clarity: Focus on conveying the message effectively.
Example: He’s not only smart but also funny.
