blather (also blether)
verb [v] ~ (on) (about sth) (informal, especially BrE) to talk continuously about things that are silly or unimportant:
What are you blathering on about now?
blather (also blether) noun [U]
- blather on about something
- blather about something
I think that not only the first sentence but the second is grammatically correct. Is the first more common?
