Ready maxim for Boy Scouts (2,8)
I believe the answer is:
be prepared
'ready maxim' is the definition.
The definition suggests an adjective which matches the answer.
'boy scouts' is the wordplay.
I cannot really understand how this works, but
'boy' could be 'red' and 'red' is found in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for be prepared that I've seen before include "Boy Scouts' motto" , "Scout motto" .)
