Force open commonplace letter for barrister in the Strand (6)
I believe the answer is:
breach
'force open' is the definition.
(thesaurus)
'commonplace letter for barrister in the strand' is the wordplay.
I cannot quite see how this works, but
'letter' could be 'r' and 'r' is found within the answer.
'strand' could be 'beach' (I've seen this in another clue) and 'beach' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for breach that I've seen before include "Gap (in defensive wall)" , "Violation, maybe of the peace" , "Disturbance as of the peace" , "Severance" , "Failure to follow the rules" .)
