Level 4 - Lesson 5 - Flashcards. "I couldn't come" is translated (by you) as "Non sono potuto venire". Totally confuses me, since Potere is conjugated with Avere, not Essere. It seems to me that it should be "Non ho potuto venire". Does the past participle take the auxiliary of Venire even though it is used with Potere????? That doesn't make sense to me. Help.
