Relating to or characteristic of Alcibiades or his behavior; marked by brilliance combined with recklessness, impulsiveness, or moral ambiguity.
From Alcibiades, the famous ancient Athenian general (450-404 BCE), + -ean suffix (meaning 'of or relating to'). The term captures his reputation as a charismatic but unpredictable leader.
Alcibiades was so clever and charming that Athens loved him, but so reckless that he betrayed them multiple times—so 'alcibiadean' describes anyone brilliant but dangerously unreliable, making it a perfect insult for a genius troublemaker.
