、。
She's not only kind but also honest.
Literal
She [topic-は], kind [not only-だけでなく] honest.
The pattern ~だけでなく ('not only X, but also Y') adds a second quality on top of the first, implying she exceeds expectations. In this sentence, だけ attaches after the na-adjective's attributive form (親切な + だけでなく). The comma after は creates a subtle pause, giving the praise a measured, deliberate tone. This pattern is versatile — it works with nouns, verbs, and adjectives alike.
