Talks rubbish about an alternative to 1 (6)
I believe the answer is:
waffle
'talks rubbish' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for waffle that I've seen before include "that you may have at breakfast, say" , "something for breakfast" , "Cake; speak vaguely" , "Talk nonsense - breakfast cake" , "Flannel" .)
