“…I am spoil'd, 'undone' by villains!” <aq>Shakespeare, 'Othello' (1603–05)</aq>
My shoelace is 'undone'. = My shoelace has 'come undone'.
There were still some tasks 'left undone'.
(..) But there were some who resisted. And on the slopes of Mount Doom,they fought for the freedom of Middle-earth. Victory was near. But the power of the Ring... ...could not be undone. It was in this moment... ... when all hope had faded... ... that Isildur,son of the king,took up his father's sword. (..)2001 The Lord of the Rings: The Fellowship of the Ring
