To go round enclosure order permit (9)
I believe the answer is:
encompass
'to go round' is the definition.
(thesaurus)
'enclosure order permit' is the wordplay.
'enclosure' becomes 'enc' (abbreviation as in letters).
'order' becomes 'om' (Order of Merit).
'permit' becomes 'pass' (pass is a kind of permit).
'enc'+'om'+'pass'='ENCOMPASS'
(Other definitions for encompass that I've seen before include "ring" , "Contrive" , "Hold within" , "Surround, hold" , "Comprehend" .)
