Ludwig's WRAP-UP
The phrase "once existed" is a common and grammatically sound way to describe something that was present in the past but is no longer so. As Ludwig AI confirms, this phrase is widely accepted and used in various contexts. It functions primarily to provide historical context and distinguish past conditions from present realities. While the phrase maintains a relatively neutral tone, it can be useful to consider alternatives like "used to exist" or "formerly existed" depending on the desired level of formality. Remember to use "once existed" only when referring to something that is truly no longer present, avoiding ambiguity with the present tense.
