Are nuts going out to take a walk! (7)
I believe the answer is:
saunter
'a walk' is the definition.
(I know that saunter is a type of walk)
'are nuts going out' is the wordplay.
'going out' indicates an anagram (out can mean wrong or inaccurate).
'are'+'nuts'='arenuts'
'arenuts' is an anagram of 'SAUNTER'.
'to take' acts as a link.
(Other definitions for saunter that I've seen before include "Walk in a slow and relaxed manner" , "Walk casually or jauntily" , "Relaxed stroll" , "To walk at a leisurely place" , "Leisurely stroll" .)
