Common error

While "is known" is generally acceptable, overuse can make writing sound passive and less engaging. Vary your sentence structure by using active voice where appropriate.

The phrase "is known" functions as a passive construction, indicating that the subject of the sentence is the recipient of the action, rather than the performer. As Ludwig AI suggests, it emphasizes the state of being recognized or understood, as seen in many examples.
