Joke leg manufactured for rambling group? (6)
I believe the answer is:
gaggle
'rambling group?' is the definition.
(a disorderly or rambling group of people)
'joke leg manufactured' is the wordplay.
'joke' becomes 'gag' (a gag is a joke or witticism).
'manufactured' indicates an anagram.
'leg' anagrammed gives 'gle'.
'gag'+'gle'='GAGGLE'
'for' acts as a link.
(Other definitions for gaggle that I've seen before include "Collective noun for geese" , "Assembly of geese" , "Group of geese" , "Cackling sound" , "Flock of geese on the ground" .)
