Calor is a Spanish term used for heat or warmth. However, there are several words that can be used as a synonym for calor, depending on the context. For instance, ardor refers to intense heat, warmth, or passion. Fiebre refers to a fever, which can also be a synonym for calor in some cases. Bochorno, on the other hand, refers to a feeling of suffocation or discomfort caused by excessive heat. However, in the context of cooking, a synonym for calor would be fuego, meaning fire. Additionally, calidez can be used as a synonym for warmth in a figurative sense, such as a warm welcome or a cozy atmosphere.
