The first definition listed for blather in the Merriam-Webster on-line dictionary is “to talk foolishly at length—often used with on.” As in, I suppose, “He really blathers on about a whole lot of nothing on his narcissistic blog.”
This category is closely related to the Bloviation category. There are important differences:
- I hope to keep my blather fairly inoffensive and less stridently opinionated than my bloviation.
- “Blather” is a fun word, but not as much fun as “bloviation.”
