In Spanish, the equivalent of ‘Oh’ is often expressed as ‘Oh’ as well. However, depending on the context, you might also hear expressions such as ‘¡Ay!’ or ‘¡Vaya!’.
For instance, when expressing surprise or realization, ‘Oh’ can simply remain the same. But if you’re reacting to pain or discomfort, ‘¡Ay!’ would be more appropriate. Similarly, ‘¡Vaya!’ can be used to convey astonishment or a mix of surprise and admiration.
It’s important to consider the context in which you want to use the expression, as the Spanish language offers a variety of interjections that convey different emotions.
