“Is this passive voice?”
I absolutely dread this question in a critique session. My grammar isn’t horrible but I am no grammar Nazi. Is it passive voice? Or did you just use a helping verb? Your guess is as good as mine. Active verbs are best. That’s all I know.
Or at least that’s all I knew until I learned about the Zombie Test.
. . . by zombies. All you need to know to detect, and get rid of, passive voice.
