jo
/ˈxo/ · B1 · intj
stop, whoa (especially when commanding a horse or imitative thereof)
🐴✋ Sounds like ho, as in whoa-ho! Same sound you'd shout to stop a horse
The Spanish j is a breathy h sound, so jo is said like English ho. English riders say whoa or ho to stop a horse, and Spanish riders say jo, which is almost the same sound. It's also used jokingly to tell a person to stop.
