Correlative conjunctions are pairs of conjunctions that work together to connect equal grammatical elements. They always come in pairs and link words, phrases, or clauses.
Here's how it works:
* "Not only" introduces the first element.
* "But also" introduces the second element, which is usually parallel in structure to the first.
Example:
* "Not only did she sing, but she also danced."
Here, "not only" connects to the clause "she sang" and "but also" connects to the clause "she danced." Both clauses are parallel in structure (subject + verb).
Other common correlative conjunctions include:
* Both... and...
* Either... or...
* Neither... nor...
* Whether... or...
* As... as...
* So... as...
* Not only... but...
