Rule reminder
Passive periphrasis summary: 'essere + pp' = state or general passive; 'venire + pp' = process/action (habitual); 'andare + pp' = obligation/necessity. In English, all three often translate as 'is/are + pp', but the nuance differs. Context, agent presence, and whether something is habitual, obligatory, or descriptive determines which Italian form to use.
