Rishi reveals John was a musical genius as he was expertly able to play the piano without ever having learnt formally.
In the above sentence, what does it mean "having"? What did it use here? Without using "having" the meaning makes sense, right? I believe "having" here used is to get causative meaning. He did not teach the piano without helping from anyone. Please correct me if I am wrong.
Thanks in advance 🙏
