“…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'.
(..) Monsieur Dumont, you must move your vehicle immediately. I am so sorry, Officer Clouseau. My chair, it won't move. Here's your problem. Your battery cable has come undone. Let me help. Let's see. The positive to the negative. The negative to the positive. There. All right, you are ready to go. (..)1976 The Pink Panther Strikes Again
