The word "fictionalized" is often used to describe a work of fiction that is based on or inspired by real-life events. However, there are several synonyms that can be used instead of "fictionalized." One option is "dramatized," which suggests that the story has been adapted for dramatic effect. Another option is "embellished," which implies that the story has been enhanced or exaggerated in some way. "Fantasized" is another possible synonym, suggesting that the work is more imaginative or fantastical than strictly based on reality. Ultimately, the choice of synonym will depend on the specific context and tone of the work in question.
