Why this word
A poseur is someone who tries to look more smart, cultured, or important than they are. In everyday English, people also say “bluffer” or “know-it-all,” but those words are more informal and often more negative. If the person is pretending to have real skill or expertise, “charlatan” can also work. Choose the word based on how serious the lie is and how formal the situation sounds.
