”I won’t speak with him” in Spanish is “No hablare con él.”
I think it’s voy....because voy means
“I’m going, I go, I arrive....etc”
So your sentence is...
Yo no voy llegar a las de la tarde.
Translation:
“I'm not going to arrive in the afternoon.”
The word is prohibe, for example se prohibe ir al armario durante la clase
