Rob from Norfolk town gathers groups of friends together (10)
I believe the answer is:
dispossess
'rob' is the definition.
(thesaurus)
'norfolk town gathers groups of friends together' is the wordplay.
I cannot quite understand how this works, but
'groups' could be 'posses' and 'posses' is present in the answer.
'town' could be 'diss' (town in Norfolk) and 'diss' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'from' is the link.
Can you help me to learn more?
(Other definitions for dispossess that I've seen before include "Expel" , "Deprive (someone) of land/property" , "Drive out l" , "Deprive of land and property" .)
