Call for truce heard in scout groups (5)
I believe the answer is:
packs
'groups' is the definition.
The answer is an example.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for packs that I've seen before include "Crowds" , "Given cards" , "prepares to leave" , "lots of cards" , "Prepares gifts, say" .)
