El Aula – Calor, Caluroso, or Caliente – What Do They Mean?

Calor, Caliente and Caluroso.sun scale

It is understandable why these three words are some of the most searched for words on Google. In all of the years that we have taught Spanish, they have been a source of great confusion to all of our students at some time in their learning journey.

The fact is that to really understand how these words work you must first know that one of them is a noun and the other two are adjectives.


Let’s deal with the noun first. Calor actually means ‘heat’ and not ‘hot’. This is usually where the confusion comes in. Often students want to say: “This coffee is hot.” and rather than saying that they use ‘calor’ and say: “This coffee is heat.” or worse still, “This coffee is a lot of heat.”

So, ‘calor’ is used when talking about when it is hot (the weather) however, Spanish speakers do not actually say: “It is hot.”, but rather they say: “It makes heat.”

Also, if you want to say, “I am hot.” In Spanish, you cannot say it the same way as you do in English. Because Spanish speakers actually say, “I have heat.”

In fact, if you were to say literally, “I am hot.” in Spanish, you would actually be saying, “I am horny.” (Estoy caliente.) So, unless you were with someone who might find that comment interesting, it is better not to get them mixed up, don’t you think?


This word ‘ caliente ‘ is an adjectives and it translates as “hot”. This is the word that you use when you want to describe the actual temperature of objects. For example, you use ‘caliente’ when you are talking about something that is hot to touch, like, a cup of coffee, a fire, a radiator, etc.

To intensify the word ‘ caliente ‘ you use the word “very” which in Spanish is ‘muy’.

So to saying the coffee is very hot. You would say: El café está muy caliente.

Once again, there is some confusion with the intensifiers that we use with ‘caliente’ and ‘calor’.

With ‘calor’ we use the intensifier, ‘mucho’, which is ‘a lot’. Many students get these two intensifiers mixed up and so they often say sentences like: “I have very heat.” Or “The fire is a lot hot.”


Like ‘ caliente ‘, ‘caluroso’ also is an adjective and has a very limited use in the Spanish language. Principally it is used when talking about what kind of day it is, when referring to the weather. For example, you can say: “It is a warm day.” (Es un día caluroso.) However, aside from this particular use, the word ‘caluroso’ so is not used a great deal.

Our advice is very much that you stick to the main two words when describing the weather (calor) and the temperature of objects (caliente).
