The Proper Use of Commas in "Not Only But Also" Constructions
Understanding how to correctly punctuate "not only but also" is a crucial aspect of English grammar that often confuses writers at all levels. This guide will explain when to use commas with this common correlative conjunction pair, providing clear examples and practical applications to help you master this grammatical structure.
Understanding "Not Only But Also" as a Correlative Conjunction
The phrase "not only but also" functions as a correlative conjunction, which means it works in pairs to connect two elements in a sentence. These elements can be words, phrases, or complete clauses. The primary purpose of this construction is to show that something is surprising, additional, or more significant than initially thought.
When using "not only but also," the structure typically follows this pattern: "Not only [first element], but also [second element]." The key question for punctuation is determining when to place a comma before "but also."
When to Use a Comma Before "But Also"
With Independent Clauses
The most straightforward rule for comma usage with "not only but also" involves independent clauses. An independent clause contains a subject and a verb and can stand alone as a complete sentence.
Correct usage: When "not only but also" connects two independent clauses, place a comma before "but also."
Examples:
- Not only did she finish the project early, but also she received a promotion.
- The team not only won the championship, but also set a new scoring record.
In these sentences, both parts could function as separate sentences. The comma helps readers process the transition between the two independent ideas That's the whole idea..
With Complex Sentences
Even when one part of the sentence is more complex, if both elements are independent clauses, the comma should still precede "but also."
Examples:
- Not only does he have a degree in engineering, but also he speaks four languages fluently.
- The company not only expanded its operations overseas, but also launched several new product lines.
When Not to Use a Comma Before "But Also"
With Single Words or Phrases
When "not only but also" connects single words or simple phrases that aren't independent clauses, omit the comma.
Examples:
- She is not only intelligent but also kind.
- The book is not only informative but also entertaining.
In these cases, removing the comma creates a smoother, more natural reading experience. The connection between the words is immediate and doesn't require the pause that a comma provides.
With Prepositional Phrases
When connecting prepositional phrases or other non-clausal elements, no comma is necessary.
Examples:
- The museum houses not only ancient artifacts but also modern art pieces.
- He has interests not only in music but also in literature.
Advanced Considerations and Common Mistakes
Parallel Structure
One of the most important aspects of using "not only but also" correctly is maintaining parallel structure. Both elements connected by this phrase should have the same grammatical form.
Correct parallel structure:
- She not only speaks English but also French. (Both are verbs)
- The report is not only detailed but also comprehensive. (Both are adjectives)
Incorrect parallel structure:
- She not only speaks English but also is fluent in French. (Mixed verb forms)
- The report is not only detailed but also was comprehensive. (Mixed adjective and verb)
Punctuation with Introductory Elements
When "not only" begins a sentence that also has an introductory word or phrase, use a comma after the introductory element, but the comma before "but also" depends on whether you're connecting independent clauses.
Examples:
- Still, not only did she solve the problem, but also she explained the solution clearly.
- Even so, not only the results were surprising but also the methodology was innovative.
Compound Sentences with Multiple Conjunctions
When combining "not only but also" with other conjunctions like "and," "or," or "but," apply standard comma rules for compound sentences along with the rules for "not only but also."
Examples:
- Not only did the students study hard, but they also participated in extracurricular activities, and they maintained good grades.
- The conference featured not only keynote speakers but also interactive workshops, and panel discussions.
