Straight from the Horse’s Mouth
“Straight from the horse’s mouth” means information received directly from the most authoritative or original source. The racing explanation is plausible context, while reviewed specialist evidence reports printed use by 1896 without proving who coined the expression.
It means information obtained directly from the person or source best placed to know. Phrase Finder reports a Reynolds’s Newspaper example from June 1896 and connects the expression with racing information, but that does not establish a single inventor.
