Frequently asked questions
Why doesn’t Word flag passive voice by default?
It’s a style preference, not a grammar error, so it’s off by default.
What’s a good passive sentence percentage?
Many writing guides suggest keeping it low, often under about 10%, but it depends on your field and audience.
Can Google Docs check passive voice?
Google Docs doesn’t have a built-in passive voice check. Browser add-ons and writing assistants can help.
