Expert writing Tips

Best practice

Prefer using "there was once" for singular subjects or "there used to be" to indicate something existed in the past but no longer does. This ensures grammatical correctness and clarity.

Common error

Do not use "there are" with "once" because "once" implies a singular instance. Instead, use "there was once" for singular instances or rephrase to avoid the error altogether.

FAQs

Is "there are once" grammatically correct?

No, "there are once" is not grammatically correct. The correct phrasing would be "there was once" for singular instances or "there used to be" to refer to something that existed in the past.

When should I use "there was once" instead of "there are once"?

Use "there was once" when you are referring to a single event or item in the past. The phrase "there are once" incorrectly mixes plural and singular forms.

What are some alternatives to "there are once" to indicate something existed in the past?

Alternatives include "there used to be", "once there was", or simply rephrasing the sentence to use past tense verbs.

How can I avoid making mistakes when using phrases to describe past events?

Pay close attention to subject-verb agreement. Ensure that singular subjects are paired with singular verbs (e.g., "there was"), and plural subjects with plural verbs (e.g., "there are"). Using "there used to be" can also help avoid these issues.
