Vipassanā is often translated as insight.
From the text we learn that it partakes in wisdom, for which it needs to be cultivated. And there lies the problem; you can't cultivate insight. At best you can cultivate other things and wait for insight to pop up so to speak but insight itself is more a case of it is there or it isn't.
In general, what would be needed for wisdom? This would be understanding right? If we don't understand then in that area is wisdom not yet to be expected. The dictionary says that vipassanā is from vi, which can be used to emphasise or intensify, and passati, to see. To really or clearly see is about the meaning, to know why or how something works, which is what understanding is.
And in general, how is understanding cultivated? We get ourselves well informed and we may have to get more familiar with it right? So like that, we pay attention to what is pointed out (which is by the way the support for right view, which is included with the mass of wisdom) and we may have to get more familiar with it. Understanding is to be cultivated so that wisdom is cultivated so that not knowing is gotten rid of.
