Walk and talk aimlessly (6)
I believe the answer is:
ramble
I believe this is a double definition.
'walk' is the first definition.
(ramble is a kind of walk)
'talk aimlessly' is the second definition.
(I've seen this in another clue)
'and' acts as a link.
(Other definitions for ramble that I've seen before include "Walk in the country - talk aimlessly at length" , "Take a country walk" , "Go as fancy leads" , "Roam about" , "Show incoherence" .)
