Run into trouble joining criminal society (11)
I believe the answer is:
brotherhood
'society' is the definition.
(thesaurus)
'run into trouble joining criminal' is the wordplay.
'run into trouble' becomes 'brother' (I can't explain this - if you can you should believe this answer much more).
'joining' says to put letters next to each other.
'criminal' becomes 'hood' (hood is a kind of criminal).
'brother'+'hood'='BROTHERHOOD'
Can you help me to learn more?
(Other definitions for brotherhood that I've seen before include "union" , "Fraternity" , "association" , "Feeling of close kinship" , "Community" .)
