Horses own the winner’s circle in English idioms. But where did these popular phrases originate?
1. Hold your horses!
When It Originated: 800 BCE

One of the oldest aphorisms in English, this adage was first recorded in the Old English Homilies: “Hwa is thet mei thet hors wettrien the him self nule drinken.” A modern version appeared in the 1602 play Narcissus: “They can but bringe horse to the water brinke / But horse may choose whether that horse will drinke.”
4. Horseplay
When It Originated: 1580s
In the 16th century, “horse” was a common adjective describing anything strong, big, or coarse. Along with horseplay, that’s how horseradish got its name.
