A person who blathers excessively; a foolish, talkative person who speaks nonsense.
From 'blather' combined with the suffix '-skite,' likely influenced by Scottish or Northern English dialects. The '-skite' element may relate to 'skate' (a disreputable person) or be purely expressive for dramatic effect.
'Blatherskite' is one of English's most delightfully weird insults—it sounds like it should mean something dangerous, but it just means someone who won't stop talking! American newspapers loved this word in the 1800s for mocking politicians.
