How to use not only...but also - 1

Not only...but also is a correlative conjunction used to connect two ideas or elements that are related or contrasted. Here's how it works:

1. Structure
The structure is not only...but also.

Both parts need to be parallel in structure, meaning they should have the same grammatical form
(e.g., noun, verb, adjective).
Example: She is not only intelligent but also hardworking.
Intelligent and hardworking are both adjectives, so the structure is parallel.

2. Placement
Not only usually precedes the first element, and but also comes before the second element.
Example: Not only did she finish the project on time, but she also exceeded expectations.
Not only did she finish is the first element, and but she also exceeded is the second element.

3. Usage
Adding Emphasis
It's used to emphasize the importance or significance of both elements.
Example: This car is not only fast but also fuel-efficient.
Contrast or Alternatives
It can also show a contrast or provide alternatives.
Example: He can not only play the piano but also the violin.

4. Inversion with "Not only"
When not only starts a sentence, there's often subject-verb inversion, especially in formal writing.
Example: Not only did they win the championship, but they also set a new record.
Did they win is the inverted form.

Overall, not only...but also is a versatile structure that helps in adding emphasis, showing contrast, or presenting alternatives in sentences.
