Grammar: have impact 'on' or 'for'? Thanks! Hi, could anyone please help me with the following question? I am quite confused. Here are 2 examples about 'impact': 1. Unfortunately, it is not always the case that new things are promoted because they have good impacts for the majority of people. 2. 'Protect IP Could Have Far-reaching Impact on Digital Freedom'..... Are both 'for' and 'one' correct? Or I can only use 'for' when the object is 'people'? Thanks!!!!
