Are you a fan or a fanatic?

What is the difference between ‘fan’ and ‘fanatic’? (Vikram Das, Delhi)Considering the fact that ‘fan’ is actually the abbreviated form of ‘fanatic’, there should be little or no difference in meaning

Considering the fact that ‘fan’ is actually the abbreviated form of ‘fanatic’, there should be little or no difference in meaning between the two words. This, however, is not the case. People in general prefer to be called a ‘fan’ rather than a ‘fanatic’. Both words suggest that the individual is an enthusiastic or a strong supporter of something. When you say that you are a fan of the Chennai Super Kings or the Mumbai Indians cricket team, what you are suggesting is that you enthusiastically support the team, and enjoy watching them play. During the course of a match, you may cheer every time one of your players does well, and boo the star player from the opposition when he walks out to bat. These are some of the ways you show your support for your team. Similarly, when you claim to be a fan of Roger Federer or Virat Kohli, you are stating that you are a great admirer of the individual. You may have lengthy arguments with your friends as to why you believe that he is the best player of all time. The word ‘fan’, in most cases, has a positive connotation. I had a really good time talking to a few Rajesh Khanna fans.
