Three concepts in this chapter need to stay distinct:
ExampleCharacteristicMain point
اِنْصَرَفَIntransitivityNo required direct object
كَسَرْتُهُ فَانْكَسَرَResulting actionResult follows the first act
اِنْطَلَقَIndependent senseLexical meaning stands alone
Not every intransitive verb necessarily illustrates a cited cause-and-result pair. Nor must an independent lexical use be forced into an unstated causative story.
