Written by Roger R. Henderson
The letter ‘O’ in Spanish horse names brings a wonderful roundness and openness, like the shape of the letter itself. From “Oro” (gold) to “Océano” (ocean), these names carry a sense of completeness and possibility. There’s something inherently optimistic about ‘O’ names – they seem to embrace the world with the same wholehearted enthusiasm that horses bring to their galloping.
One of the most striking horses I ever encountered was a golden palomino stallion named “Oro.” His owner, an elderly Spanish gentleman, told me he’d waited forty years to find a horse worthy of that name. When the sun hit Oro’s coat, he truly looked like he’d been dipped in liquid gold. It was a reminder that sometimes the simplest names carry the most power – and Spanish ‘O’ names have that perfect blend of simplicity and significance.
