Expert writing Tips
Best practice
Use "which indicate" to introduce non-essential information that provides additional detail or clarification, setting it off with commas.
Common error
Avoid using "which" when "that" is more appropriate. "Which" introduces nonrestrictive clauses (providing extra, non-essential information), while "that" introduces restrictive clauses (essential to the sentence's meaning). Using "that indicate" may be more appropriate when the clause is essential for defining what is being discussed.

FAQs
How do I use "which indicate" in a sentence?
Use "which indicate" to introduce a nonrestrictive clause that provides additional, non-essential information. This clause should be set off with commas. For example: "The test results, "which indicate" a positive outcome, will be reviewed."
What can I say instead of "which indicate"?
You can use alternatives like "that demonstrate", "that suggest", or "that signify" depending on the context.
Is it always necessary to use a comma before "which indicate"?
Yes, a comma is typically required before "which indicate" when it introduces a nonrestrictive clause. This comma signals that the information is additional and not essential to the sentence's core meaning. Without the comma, the sentence could be grammatically incorrect or confusing.
What's the difference between using "which indicate" and "that indicate"?
"Which indicate" introduces a nonrestrictive clause, providing extra information, while "that indicate" introduces a restrictive clause, which is essential to the sentence's meaning. Consider whether the clause can be removed without changing the sentence's core meaning; if so, use "which".
