hamartia means originally a 'bad shot' or 'error', but is currently used for 'offence' or 'sin'.
That is not unmotived, however; it is of Aspatia's own choosing and of Amintor's hamartia.
The pathetic devotion of Aspatia is essential to our understanding of Amintor's tragic weakness, his hamartia.
Greek, literally "fault, failure, guilt," from hamartanein "to fail of one's purpose; to err, sin," originally "to miss the mark."
