What do you mean by active and passive voice?

What do you mean, what do I mean? Did I use the expression "active and passive voice"? I don't think so. No, you want to phrase your question "What is meant by the active and passive voice?", because that way you don't have to say who is using those Words. You see, normally if you say something like "B. King is discussing active and passive voices" you have to say that it is B. King that is doing it, but if you don't know or don't want to say, you can turn it around backwards so it says, "Active and passive voices are being discussed." There. You don't know from that who is discussing it, do you?

Perhaps you would like to know what this turning around backwards is called? It's called the passive voice. Yes, I asked you to rephrase your question so it was in the passive voice ("What is meant by the active and passive voice?") rather than the active voice ("What do you mean by active and passive voice?").
