Club together with the role snacks play (5,5)
I believe the answer is:
close ranks
'club together' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'with the role snacks play' is the wordplay.
'with' means one lot of letters go next to another.
'play' is an anagram indicator.
'role'+'snacks' is 'rolesnacks'.
'rolesnacks' anagrammed gives 'CLOSE RANKS'.
Can you help me to learn more?
(Other definitions for close ranks that I've seen before include "Display solidarity" , "to put taxi firms out of business?" , "Unite as a defensive measure" , "make cabbies go out of business?" , "Unite in order to defend common interests" .)
