On Not Only but Also?

When using not only . . . but also in a sentence, parallelism should be the goal. It means that the words following both parts of this correlative conjunction (i.e., not only and but also) should belong to the same parts of speech. For example, if a verb follows not only, then a verb should also follow but also.

How do you use not only but also?

Not only was it raining all day at the wedding but also the band was late. Not only will they paint the outside of the house but also the inside. When there is no auxiliary verb or main verb be, we use do, does, did: Not only did she forget my birthday, but she also didn't even apologise for forgetting it.

Do you have to say but also with not only?

You can start a sentence with not only, but it must be followed by not also. This is because the expression not only..but also is a correlative conjunction that helps create parallelism, or balance, in a sentence.
