A taint, stain, or mark of disgrace; the condition of being attainted or disgraced.
From attaint + -ure suffix (like 'capture' or 'departure'). This variant appeared in Middle English legal documents and literature as an alternative to 'attainder,' emphasizing the stain or mark left by dishonor.
This is an archaic legal-poetic term that basically means 'the permanent mark left on your reputation'—it appeared frequently in Elizabethan plays where characters obsessed over whether they could escape the attainture of a parent's crimes.
