When you’re trying to convey unexpected but related information or emphasize a surprising fact, you might find yourself using not only…but also. This word pairing is useful when linking two closely connected clauses or other elements of a sentence.
If you find this two-part expression working its way into your writing repertoire, here are a few things to keep in mind.
What Does not Only but Also Mean?
Constructing a Sentence With not Only but Also
In a sentence, the actual construct of the expression looks like this: not only this…but also that. This and that represent the information, facts, or ideas that are being expressed in each phrase.
In this example, the two pieces of related information revolve around where a young girl made friends. While making friends at the park may seem commonplace, making friends at the dentist’s office is unexpected.
Creating Connections: not Only but Also as a Part of Speech
Other Correlative Conjunctions
Other correlative conjunctions include:
In each of these examples, the correlative conjunctions serve to highlight the relationship between elements in the sentence. For the first sentence, that would be chocolate ice cream and raspberry sorbet. In subsequent sentences, that would be the plaid skirt/red pants, the campus newspaper/literary magazine, and going to college/pursuing acting.
Creating Parallelism with not Only but Also
Some grammarians, editors, and writers believe that not only…but also must be used with parallel structure. Others disagree, arguing that it’s more a question of style.
When using not only…but also, parallelism means that each part of the phrase should be followed by the same parts of speech. In other words, if a noun follows not only, then a noun should follow but also, as well. If not only is followed by a verb phrase, then but also should be followed by a verb phrase, too.
In this example, each part of the not only…but also expression precedes a verb phrase for parallelism.
In this example, a noun phrase follows both not only and but also to maintain parallelism.
Do you Have to use but Also With not Only?
Well, it depends. In formal writing, it’s probably a good idea to stick with the traditional not only…but also structure. With less formal writing, writers may choose to omit the word also, so the phrase becomes: not only…but. The meaning of the sentence should remain unchanged.
Although the meaning between the two sentences remains essentially the same, readers may perceive the second sentence as slightly less formal.
In another variation of not only…but also, a noun or pronoun may be inserted between but and also.
In this example, the words she is have been inserted between but and also to create a better flow.
Note: Although but also can be split, the same doesn’t hold true for not only. The first word pair in this two-part expression should never be split.
Not Only but Also: Comma Considerations
You knew commas would fit in somewhere, right? Not to worry, because there’s a simple rule to follow when punctuating not only…but also.
Since not only…but also is a correlative conjunction, no comma is necessary when punctuating the pair.
Note: Although no commas are needed when punctuating this pair, commas may be added in special circumstances for extra emphasis.
Replacing not Only: Synonyms for This Formal Pair
Not only…but also can feel too formal for some styles of writing. If less-formal wording seems more appropriate, there are other options.
Try replacing not only…but also with transitional words or phrases such as:
- In addition to
- Equally important
- As well as
And, there are plenty more where those came from.
Nuances of Meaning
Whenever you select words, you’re choosing nuances in meaning. By opting for a different word or phrase, you may alter the meaning of your sentence ever so slightly. You may also alter the tone of your prose, making it less formal or more conversational.
The Issue of Rephrasing
Some sentences may also require restructuring or rephrasing in order to accommodate a change of vocabulary.
This sentence shows the correct usage of not only…but also. There are, however, other ways of expressing a similar sentiment.
When comparing these sentences, you may notice that the emphasis changes, placing importance on one of the phrases more or less. The meaning of the sentence may change accordingly.
Matters of Style: Closing the Book on not Only but Also
Some writers may consider not only…but also to be one stylistic choice among many. After all, there are multiple options for linking two related thoughts, with each creating different shades of meaning.
Whether you opt for this phrase or another one is up to you, and it may depend on the type of writing you’re doing. Most importantly, your sentence should not only sound natural but also be clear in meaning. That, above all, is what writing should be about.
