> What's the term for someone who gives opinions on topics they know nothingabout?And the answer: Ultracrepidarian. Photo credit: installect[https://installect.wordpress.com/2013/02/21/ultracrepidarian/]."Ultracrepidarian" is one of those polite words that describe impolite people.The word most likely comes from Latin words meaning "beyond the shoe," and thephrase "the cobbler should not judge beyond his shoe."The need to describe impolite individuals has existed since antiquity. As thestory goes, the famed Greek painter Apelles one day heard a cobbler criticizingthe way he had rendered a foot in a painting. While his response has since beenlost to time, we might imagine that ultra crepidam, a Latin phrase meaning"beyond the sole," factored into his rebuke. Today, the phrase can be used to describe someone that attempts to express anopinion about a subject on which they have no knowledge. An example might be:> Ugh! John is being such an ultracrepidarian today. He watched a two-minuteYouTube video on dinosaurs and thinks he's an expert!Other colorful words for annoying or impolite people include a smatchet, acumber-world, and a flibbertygibbet (no, we're not just making those up).
