Expert writing Tips

Best practice

When you intend to use a relative clause, ensure the verb tense agrees with the context. Use "which is" for present tense and "which was" for past tense. Avoid the grammatically incorrect "which is was".

Common error

Avoid mixing present and past tenses within a relative clause. The phrase "which is was" incorrectly combines present and past forms. Always check that your verb tenses are consistent and grammatically correct.

In summary, the phrase "which is was" is a grammatically incorrect construction that combines present and past tenses inappropriately. Ludwig AI identifies it as an error. While examples of its usage exist across various sources, including News & Media and scientific publications, it is crucial to avoid this phrase in formal writing.

FAQs

How do I correctly use "which is" or "which was" in a sentence?

Use "which is" to describe a current state or characteristic: "The car, "which is" red, belongs to him." Use "which was" for a past state: "The restaurant, "which was" popular, closed down."

What's the difference between "which is" and "which was"?

"Which is" refers to the present, while "which was" refers to the past. For example, "The house, "which is" on the corner, is for sale" (present) versus "The house, "which was" on the corner, burned down" (past).

Can I use "that is" or "that was" instead of "which is" or "which was"?

Yes, you can often use "that is" and "that was" as alternatives, but "which" typically introduces nonrestrictive clauses (adding extra information), while "that" introduces restrictive clauses (essential to the sentence's meaning). "The book, "that is" on the table, is mine" (essential) vs "The book, "which is" interesting, is also informative" (extra information).

What are common mistakes to avoid when using relative clauses with "which"?

A common mistake is using incorrect verb tenses, like the incorrect phrase "which is was". Ensure the verb tense matches the context. Also, avoid using "which" for essential clauses; use "that" instead. For instance, avoid "The car, which got a flat tire, needs repair" when "that got" is what you need.
