Expert writing Tips

Best practice

Always double-check the structure when using "that", "is", and "was" together. Ensure "that" is followed by a subject (like "it") to create a grammatically sound sentence.

Common error

Avoid combining "that is" directly with a past tense verb form. Instead of saying "that is was", restructure the sentence to include the proper subject and verb conjugation, such as "that it was".

Always ensure the sentence structure includes a subject between "that" and "was" to maintain grammatical accuracy. Avoiding this phrase in formal writing will enhance clarity and credibility.

FAQs

In standard English, "that is" doesn't combine directly with a past tense verb. The phrase requires a subject like "it" to form a proper clause, such as "that it was".

How can I avoid using "that is was" in my writing?

Pay attention to sentence structure when using "that", "is", and "was". Ensure there's a subject (usually "it") between "that" and "was" to maintain grammatical correctness. For example, "I thought that is was a good idea" should be "I thought that it was a good idea".

Is there any context where "that is was" might be acceptable?
