What is it the word (I think verb) when someone bluffs to make a story more interesting or believable?

Thank you, tutors, for sparing your time to review my question.

I got the word calumniation when I looked in a thesaurus.

Oh, right. Thank you, tutor Writeacher, for answering my question. Much appreciated~

The word you are referring to is "embellish." When someone embellishes a story, they add details or exaggerate certain aspects in order to make it more interesting or believable. It is a common technique used in storytelling, where people may fabricate or enhance certain elements for dramatic effect or to captivate their audience. To find the answer to your question, you could have used an online search engine like Google and looked up synonyms for "bluffs" or "fabricates" to find the word "embellish." Additionally, a thesaurus or dictionary could have provided you with alternative words that convey the same meaning.
