In Spanish, the word for ‘raining’ is lloviendo. This term comes from the verb llover, which means ‘to rain.’
To explain a bit further, the Spanish language often uses gerunds to describe ongoing actions, similar to English. When you want to say something is actively happening, like it is ‘raining,’ you use the gerund form of the verb. Thus, when you say está lloviendo, you are expressing ‘it is raining’ in a way that clearly indicates the action is currently taking place.
