Hola, The causative verbs show that somebody or something is indirectly responsible for an action. The subject doesn't perform the action itself, but causes someone or something else to do it instead. And it is formed by verb to have + object + verb in participle For example: He had his jacket cleaned yesterday, or He got his jacket cleaned yesterday. To put the same sentence in the passive form it would differ in structure but mean the same : object + to be + verb in participle His jacket was cleaned yesterday. In both cases the subject doesn't perform the action. I hope the difference is clear:)

What's the question? Passive voice is an important topic. You need to understand how to use it, and how NOT to use it. English writing classes often beat into our heads to never ever use passive voice. That's wrong, though. Some people learn to write everything in passive voice, which is bad, but sometimes there is a reason for it. As a writer of English, you need to know how to do both. The following example of active and passive voice should make it clear the advantages and problems involved: Active: We made mistakes. Passive: Mistakes were made. Can you imagine a politician saying that second sentence? Me too. Generally using active voice is better becasue it's direct and strong, but sometimes for diplomacy it may be better to use the indirect tone of the passive voice. But was that your question?
