Third person singular of rescue, or plural noun; saves from danger or distress, or acts of saving.
From Old French rescourre 'to free, deliver,' from re- 'again' + escourre 'to shake out, discard,' from Latin excutere. The idea is literally 'to shake free again' from danger or captivity.
The etymology of 'rescue' contains the beautiful image of shaking someone free from their bonds - like shaking fruit from a tree, we 'shake' people loose from whatever traps or threatens them, giving them freedom again.
