 preemption logic is triggered for the pending Pod. Let's call the pending Pod P.
 Preemption logic tries to find a Node where removal of one or more Pods with
 lower priority than P would enable P to be scheduled on that Node. If such a
-Node is found, one or more lower priority Pods get deleted from the Node. After
+Node is found, one or more lower priority Pods get evicted from the Node. After
 the Pods are gone, P can be scheduled on the Node.
