To repeat the same words or ideas over and over again in a boring or unnecessary way.
From Greek battologia, combining battos (stammering) and logos (speech). The term emerged in rhetoric to describe tedious repetition, and the British spelling with 's' follows standard UK conventions.
Battology was named after a Greek poet named Battus who was famous for his repetitive, pointless style—so the word literally means 'to do what Battus did.' It's a deliciously specific insult for boring speakers!
