Detester

A detester is a person who detests something—someone who feels intense dislike, disgust, or aversion toward a person, idea, action, or object. The term signals a stronger emotion than ordinary dislike and can apply to moral judgments as well as preferences.

Etymology: Detester is formed from the verb detest, with the agentive suffix -er. Detest comes from Old French detester, which in turn derives from Latin detestari meaning to detest or to curse.

Usage: In modern English, detester is relatively uncommon; more typical constructions are "someone who detests X" or "a detester of X." The noun is generally neutral in its core meaning but can carry a subjective tone depending on context or emphasis.

Examples: He was known as a detester of tyranny and cruelty. She is a prominent detester of needless bureaucracy. The label can be used descriptively or evaluatively, depending on the writer’s stance.

See also: detest (verb); abhor, loathe, hate; hater (informal). The concept fits within discussions of strong negative attitudes toward people, practices, or ideas, and may appear in linguistic notes about agent nouns formed from verbs.
