the gaining of familiarity
Original Dramatica Definition
Experience refers to the cumulative effect of observing or participating in mental or physical activities until they become familiar. However, just because the activities become second nature does not mean a character is necessarily good at them. To excel, a character needs both Experience AND the innate Skills that can be honed by that experience. If either is lacking or deficient, the character's real ability will be less than its Experiential potential.
syn. familiarization, level of practice, seasoning, accumulated feelings, accumulated dealings with
