Why this word is great
ULTRACREPIDATE — [Verb] To venture beyond one's competence or purview, especially in offering criticism. From the Latin ultra crepidam ("beyond the sandal"), alluding to the Greek painter Apelles' response to a cobbler's critique, as recorded by Pliny the Elder. Unlike "pontificate" (which cloaks ignorance in grandiosity) or "meddle" (which trespasses without pretense of wisdom), "ultracrepidate" is the sin of the armchair critic, the dilettante who mistakes proximity for authority. It is the tech bro explaining virology, the pundit dissecting ballet, the stranger at the bar holding forth on your marriage—each a small tragedy of misplaced confidence, proof that expertise, like a sandal, only fits the foot it was made for.
