Expert writing Tips
Best practice
When describing the existence of something, use the active verb form "exists" instead of the passive and grammatically incorrect "is existed". For example, prefer "This phenomenon exists" over "This phenomenon is existed".
Common error
Avoid using passive voice constructions when a more direct active voice is clearer and grammatically correct. "Is existed" is a common error arising from attempting a passive construction where it doesn't fit. Using "exists" directly resolves this.

Ludwig's WRAP-UP
The phrase "is existed" is a common grammatical error, stemming from the misuse of the verb "exist" in a passive construction. As Ludwig AI clarifies, "exist" is an intransitive verb and therefore should not be used in the passive voice. While frequently encountered in various sources, especially in science and news media, its usage is incorrect. Instead, it's advisable to use the active verb form "exists" or alternatives like "is present" or "is in existence", ensuring grammatical correctness and clarity in writing.
