Translate to Spanish: (i) It's difficult to do. (ii) It was hard understanding him
I never know whether to use the (a)infinitive, (b)para or (c)de!!
eg. Es difícil hacer. Es difícil para hacer. AND/OR Es difícil de hacer. ???
Another example... It's diffiuclt to predict.
So bonus points if anyone can tell me when to use infinitive, de or para after an adjective, like the 2 sentences above!!
