Interestingly, the word 'person' did not originally refer to the individual in the way we tend to use it today. Instead, 'person' came, via french, from the Latin word 'persona', which referred to the mask worn by tan actor to protray a particular character. In this theatrical sense, personality has to do with the role or character that the person plays in life's drama. The person's individuality, in this sense, is a matter of the roles or characters that he or she assumes.
