Why should you omit "certainly" in a sentence?

More often that not, you can remove the phrases certainly and almost certainly from your work. Your writing will be clearer and more concise without them.

Example 1

• Original: I certainly didn't think those young boys should be out so late.
• Rewrite: I didn't think those young boys should be out so late.

Example 2

• Original: It's almost certainly time for dinner.
• Rewrite: It's time for dinner.
