This document discusses the proper use of the phrase "not only...but also". It provides three rules: 1) the sentence must present two pieces of information, 2) the first part comes after "not only" and the second after "but also", and 3) the two parts must use parallel structures like comparing nouns to nouns. It then gives three examples of constructions using adjectives, nouns, and verbs respectively to illustrate parallel structures.
