Hey,
I was wondering why this sentence from one of the lessons from “talking about the future” doesn’t start with vão:
Vai haver palhaços? (Are there going to be clowns?)
The sentence is reffering to clowns in plural, so why is the verb ‘ir’ takes a singular form and not plural - Vão haver palhaços?
Olá, @bldotan! When used impersonally, in the sense of existing, the verb haver is only conjugated in the third-person singular. Any auxiliary verb also needs to be conjugated accordingly, regardless of any plural nouns that follow. Even native speakers get this wrong all the time, by the way 
That would be a useful sub-note on the flash card Joseph!
Thank you Joseph!
