 Usage: -- To Irritate, Provoke, Exasperate. These words express different stages of excited or angry feeling. Irritate denotes an excitement of quick and slightly angry feeling which is only momentary; as, irritated by a hasty remark. To provoke implies the awakening of some open expression of decided anger; as, a provoking insult. Exasperate denotes a provoking of anger at something unendurable. Whatever comes across our feelings irritates; whatever excites anger provokes; whatever raises anger to a high point exasperates. “Susceptible and nervous people are most easily irritated; proud people are quickly provoked; hot and fiery people are soonest exasperated.”  --Crabb.
