We use parallel structure to make sure each item in a list (either bulleted or within a sentence) grammatically matches the others. It’s easier to read, flows more naturally and is more memorable in the mind of the reader. That sentence that you just read? Each of those three items in the list started with a verb (“is,” “flows,” and “is”). You’re welcome.
Here’s an example of a list breaking parallel structure.
When you sign up for Hudl, you can:
- Upload and watch video.
- Analyze your stats.
- Sharing playlists with your athletes.
That last bullet point made you cringe, right? Keep parallel structure in lists, whether in a single sentence, a headline or subhead, or across bullet points. Don’t make your reader cringe.
