Why does the lesson say to use Hay with “It is foggy” but Está with “It is sunny”? I would think both would use Está  

Also the lesson says to use Hay when it is followed by a noun, but Foggy is an adjective. 

Thanks for your help!

iHola!

Could you please clarify the point:

No se marcha porque está cansado (No se marcha y la causa es que está cansado)

No se marcha porque esté cansado, sino porque se ha enfadado (Se marcha y la causa no es que está cansado)

I've come upon a sentence:

No vino porque no quisiera, sino porque no pudo (The translation says: He did not come not because he didn't want, but because he could not) 

So I wonder if it really says that somebody didn't come. I guess one "not" is missing

Regards,

Alexander

Jugué al tenis ayer.
I played tennis yesterday.

Where does the 'al' come from here?

Thanks
