one's ability based on what is allowed
Original Dramatica Definition
Permission means Ability limited by restrictions. These constraints may be self imposed or imposed by others. When a Character considers what he can or cannot do, he is not assessing his ability but the limitations to his ability. When one worries about the consequences born of disapproval or self-loathing, one halts for the lack of Permission. The frustration of a character suffering a vice-grip on his ability may eventually erupt in an explosive reaction if the noose gets too tight.
syn. constrained ability, limited capability, restricted capacity, hindered performance, allowed limitations, restrained utility
