Questions & Answers about Ele prevê chuva para amanhã.
The verb prevê looks related to ver (to see). Does it follow the same conjugation?
Why do we use para here instead of por?
Why is there no article before chuva?
Just like in English, when you refer to an uncountable noun like rain in a general sense, you leave out the definite article. The sentence just says rain, not the rain, so prevê chuva is perfectly natural.
