A genius is a person with great intelligence. The term also applies to one who is a polymath, or someone skilled in many mental areas. The term specifically applies to mental skills rather than anything else, although it is also colloquially used to denote the possession of a superior talent in any field; e.g., Diego Maradona may be said to have a genius for soccer, or Winston Churchill for statesmanship.
