Converting knowledge into wisdom

This question arises from a recent post . There is a related question on the difference between knowledge and wisdom but this is more on how wisdom (insights) can arise from knowledge. The [definition of wisdom](https://www.wordnik.com/words/wisdom) is given as an ability to discern or judge what is true, right, or lasting; insight. Therefore, learning and gaining knowledge of the Dharma without insights would not constitute wisdom by this definition. How do you gain insights so that knowledge of the Dharma becomes wisdom? What are the signs of wisdom? Sharing from the sutras or personal experience/insights are welcome.
