horny

The word 'horny' originates from the Old English noun 'horn', which referred to the hard, pointed projection on the heads of animals like cattle. The adjectival suffix '-y' was added to form a word meaning "consisting of or resembling horn," describing a hard, calloused texture. Over time, this literal sense of hardness became a metaphorical basis for describing a state of sexual arousal, drawing a parallel to the erectile tissue's firmness. This figurative usage, first recorded in the 18th century, has become the dominant meaning in modern colloquial English, while the original material-based meaning persists in more technical or descriptive contexts.
