Both nalani and i are leaving so we can go to the movie.

which is the correlating conjunction?

Both/and

Explanation:

Correlatives conjunctions are a type of conjunction that join sentence elements that are equally important, and that come in pairs but are not next to each other. Examples of correlative conjunctions are Both/and, neither/nor, not only/but also, as/as, as many/as, such/that, rather/than and whether/or.

Therefore, the correlative conjunction in the sentence “Both Nalani and I are leaving so we can go to the movie” is “Both/and” which joins the nouns “Nalani” and “I.”
