Collection of silly creatures (6)
I believe the answer is:
gaggle
'collection of silly creatures' is the definition.
The definition and answer can be both groups as well as being singular nouns.
Maybe there's a link between them I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for gaggle that I've seen before include "Cackling sound" , "Colective noun for geese" , "Alternative name for a flock of geese" , "Group of geese" , "flock of birds" .)
