Jog by, around border (8)
I believe the answer is:
boundary
'border' is the definition.
(thesaurus)
'jog by around' is the wordplay.
'jog' is an anagram indicator (I've seen this in other clues).
'by'+'around'='byaround'
'byaround' is an anagram of 'BOUNDARY'.
(Other definitions for boundary that I've seen before include "march" , "Limit; hit at cricket" , "Line marking the outer limits" , "line between states" , "Border (especially in cricket)" .)
