blatherskite
Definition: a person who talks at great length without making much sense; a person who speaks nonsense.
Origin: The word "blatherskite" originated in Scotland in the early 17th century. It is a combination of the Scottish words "blather" meaning "to talk foolishly" and "skite" meaning "a contemptible person."
Example: "I tried to listen to the politician's speech, but it was just a bunch of blatherskite."
Person who speaks nonsense is a fitting definition for "blatherskite" as both words refer to meaningless language or speech. Nonsense can refer to words or ideas that lack coherence, logic, or meaning. Similarly, a blatherskite is someone who talks excessively and unintelligibly, often about trivial or irrelevant matters. Both words suggest a lack of substance or purpose behind the words being spoken. While nonsense can be humorous or entertaining, blatherskite is often seen as annoying or frustrating, as the person speaking is wasting the listener's time and energy.
