There are three forms of anger: rage, which the Greeks also call χολή or χόλος, μῆνις and κότος. When anger arises and begins to be roused, it is called rage or χολή or χόλος. Wrath again implies that the bile endures, that is to say, that the memory of the wrong abides: and indeed the Greek word for it, μῆνις is derived from μένειν, and means what abides and is transferred to memory. Rancour, on the other hand, implies watching for a suitable moment for revenge, and the Greek word for it is κότος from κεῖσθαι.
