Question

Explain why the following are correct, gramatically:

Mis padres sugirieron que yo ->viajara<- a España. (Why you use viajara instead of viaje, viajo, etc.)

Ella espera que nosotros ->hablemos<- español. (Why you use hablemos instead of hablaramos, or hablamos.)

Si yo tengo dinero, ->iré<- a escuchar esa sinfonía. (Instead of voy or fui.)

Answer 1

second sentence hablemos is in future while  hablaramos is present and hablamos past
 third sentence ire is future voy is present and fui past
