listen= to pay attention in hearing

-----------------------
What is the meaning 'in hearing'?

Could it possibly be Listening = to pay attention by hearing? I think it is just a synonym for listening. instead of saying Listening = to pay attention by listening, it uses in hearing. Does that make any sense?

Angels is right.

The phrase 'in hearing' refers to the act of actively listening to something or someone, giving your attention to what is being said. It signifies a focused and intentional effort to receive and understand auditory information. It implies that one is not merely hearing the sound or words but is actively engaged in trying to comprehend or process the information being conveyed. So, when someone says "to pay attention in hearing," they are emphasizing the importance of actively listening and not just passively hearing.
