Origin
The phrase likely originated in early 20th-century America, rooted in horse racing and trading, where the ‘horse’s mouth’ referred to inspecting a horse’s teeth for age and health, the most reliable way to assess its value, bypassing sellers’ claims. Its earliest recorded use appears in a 1917 *Chicago Tribune* article, describing gossip as ‘straight from the horse’s mouth.’ The idiom gained traction in the 1920s, reflecting America’s racing culture, as seen in Damon Runyon’s *Guys and Dolls* stories, which use racetrack slang. Its use was amplified in the 1930s through journalism and radio, where firsthand reporting was prized, as noted in *The New York Times*. The phrase’s adoption in British and Commonwealth English came through American media, notably post-1940s, and its spread was fueled by its vivid imagery, evoking a direct equine source, and its applicability to reliability, ensuring its enduring use across English-speaking cultures, from newsrooms to casual chats.
