When someone is bombastic, they tend to use excessive and exaggerated language to impress others. Some synonyms for this term include grandiose, pompous, inflated, and verbose. One who is grandiose may use extravagant language to make their speech sound more impressive, while someone who is pompous might use language to project a sense of superiority to others. Inflated speakers use hyperbole to get their message across, and verbose individuals may use excessive words to describe something when fewer words would suffice. Ultimately, all of these synonyms describe people who use language for the purpose of sounding more impressive, but in reality, they just come across as insincere and over-the-top.
