Correlative conjunctions are conjunctions made up of two or more words that must be used together. Correlative conjunctions join words, phrases, and clauses of the same category and may only join two elements.
Here are some common correlative conjunctions:
both . . . and
either . . . or
just as . . . so
neither . . . nor
no sooner . . . than
not . . . but
not only . . . but also
whether . . . or
Both . . . and works much like and does but adds more emphasis to the statement and highlights the fact that there are two elements being presented. Both . . . and is only used to connect words and phrases, not independent clauses.
