不但……而且……
Use 不但……而且…… when one fact isn't enough and you want to pile on a second, stronger one — 'not only X, but also Y.' The second clause should escalate, intensify, or add something more impressive to the first. It's the standard progressive connector in writing and careful speech, and unlike English you usually keep both halves explicit in Chinese.
Structure
不但 [CLAUSE A], 而且 [CLAUSE B]
búdàn... érqiě...
How to Think About It
不但……而且…… is an escalator: clause B has to be a step up from clause A, not just a parallel item. If the second half is just another equal trait, you want 又……又…… instead. Also, both halves must share the same subject (or the subject moves to the front of 不但) — splitting subjects on either side of 而且 breaks the parallelism.

Common Mistake
Learners drop 而且 because English often omits 'but also,' producing a half-sentence. Chinese keeps both halves: 不但 needs its 而且 partner to feel complete and progressive.
